As regular readers will know I have been picking up bits of kit for my WS38 set radio slowly over the last couple of years. This week I was very pleased to pick up a wartime signals satchel to go with the set:I have previously looked at an example of a signals satchel here, but that example was a post war version in green canvas with white metal fittings. This example is the correct one for wartime use and will go nicely with the radio. This is officially a ‘Signals Satchel No 1’, had a stores code of ZA 6292 and was introduced on 27th May 1938. The main body of the satchel is made from pre-shrunk woven cotton webbing, with a box lid:The lid is secured with a single strap and brass buckle to secure it:The inside of the satchel is lined with cotton-drill fabric to help protect the contents:Two variations of the signals satchel can be found, one with the shoulder strap sewn to the satchel itself, and the more common variety such as this one that has a standard 37-pattern shoulder brace secured with brass buckles:The top of the satchel is printed with ‘SATCHEL SIGNALS’:The inside of the top lid is clearly marked with the date 1942 and the manufacturer ‘MECo’:The strap is also stamped:According to the instruction card the signals satchel should hold:
– 2 mics and 2 phones (one for the officer)
– 1 batteries, (spare)
– 1 hooks, brace (spare)
– The instruction card
The actual batteries and junction box should have been stored in a separate pack on the back, but by all accounts only the satchel was used for much of the time so the wireless operator actually had somewhere to carry his own personal kit!
As far as I am aware this satchel was made in both Britain and Canada. I have not seen Australian, Indian or South African examples but that does not mean there was not production in these countries.
In the aftermath of the Second World War, the British Army introduced a new radio system called (retrospectively) the ‘Larkspur’. Unlike wartime sets Larkspur used VHF frequencies so was more reliable and the cases were hermetically sealed to allow them to be used in a variety of atmospheric conditions. The radios came into widespread use in the late 1950s and early 1960s and remained in use until replaced by ‘Clansman’ in the 1970s, the old Larkspur system remained in use into the 1980s however. I have now started to put together a Larkspur set, and like my WS38 and WS88 sets this will be a back burner project, picking up items as and when I find them at a price low enough for a tight Yorkshireman!
My first piece is the subject of tonight’s post, the aerial bag for the radio:The bag is made from cotton webbing, with leather straps and buckles to secure the main pouch for the aerials, which broke down into six sections. Two pockets are fitted to the front of the bag, secured with press studs. The larger one is at the end of the bag:Whilst a smaller one is provided near the top flap:These pockets held two metal reels of cord for use as guy ropes, one aerial earthing attachment and three guy rope ground spikes. On the rear is a belt loop and a pair of leather straps and buckles:The case has large stencilled lettering on the rear, reading ‘CASE AERIAL CAT’ catalogue numbers are also provided, an old style ZA stores code and a newer NSN number:This is a starting point for a new collecting area in post war radios, there seems to be an awful lot of components to these sets compared with the earlier radio sets. They are however far cheaper than wartime sets…
I love a nice piece of British communications gear, and tonight we are looking at a really interesting new addition to my collection. The ‘Telephone Loud Speaker Control Unit’ was issued to artillery batteries during the Second World War and allowed the battery commander to communicate with the four guns in the unit and provide immediate instruction on things such as range, shell type required and corrections. Altogether the set comprised the control unit (which we are looking at tonight), batteries and four speaker/transmitter units that went out to each of the guns. The control box was in effect a miniature switchboard for a five way field telephone. As with most British Army communications kit of World War Two, the control unit is housed in a stout wooden box, with the contents painted on the lid:The box weighs 22lbs when complete, so is a heavy piece of kit. There would have been a carrying strap which is now missing (although will not be difficult to replace). Opening the box up we can see it splits into two parts, with the main switchboard in the bottom of the box and storage for headphones and microphone in the lid:Four terminals are provided to connect each of the speaker/transmitter units to. A switch beneath allows each or multiple gun sites to be chosen to speak with, a bulb lighting up to show which ones are connected:A pair of terminals are provided on the main control panel, the larger being for the microphone (which I am sadly missing):The smaller terminal allows the headphones to be plugged in:The back part of the bottom half of the box has two coiled wires with terminals:These are to attach the system to a battery box, and standard Niphan plugs are attached to the ends of the cables:The lid of the control unit holds the accessories for the set, with a tinplate cover revealing a space for the microphone:The top of the cover has details on how to operate the set, note also that this set was manufactured by Truvox, other examples were produced by Tannoy:As with the microphone, a white outline indicates where the headphones are to be stowed:These are secured in place by a webbing strap with a turn buckle:A small tinplate cover reveals a space for spare bulbs for the control box:The headphones provided are very similar to those used on other British Army radio and communications sets, with a pair of Bakelite speaker units and a wire and web harness to attach them over the operator’s head:In this great photograph we can see Lieutenant LW Spurr directing the fire of the 25 pounder guns of the 4th Field Regiment, Royal Canadian Artillery near Antwerp with one of these control units:A typical order from a Gun Position Officer to the crews of the guns might be, “HE, 117, Charge 3, zero 346 degrees, angle of sight 2 degrees, right ranging 7700, fire”. This meant the guns were to fire an HE Shell, with a 117 direct action fuze, using a charge 3, at an angle of elevation of 346 degrees deviation from the guns zero line, at an angle of elevation of two degrees, only the two guns furthest to the right of the controller are to fire and the range is 7700 yards.
Continuing the process of adding the accessories I need to my WS38 radio set, I was very pleased this week to be able to get a set of aerials and their case for a few pounds. The WS38 set uses a set of ‘F-Type’ metal rod aerials:The aerials are each four feet in length, either the thinnest aerial is used on its own, to give the radio a range of about half a mile:Or three sections are joined together to give a twelve foot aerial with a range of up to two miles. The official manual gave rather more generous maximum distances:
The aerial used consists of a single vertical rod comprising one or three Antennae rods “F” sections. The maximum range obtainable with one 4’ rod is approximately 2 miles over flat country, while up to 5 miles range may be expected with the full 12’ aerial.
This however would be in optimum conditions rather than in real life! The metal rods come in two variations, some that screw together and others that are a push fit like this set:The aerial cover is made of thin webbing, in this case by Bagcraft Ltd:Note also the faint ‘ZA’ code indicating that it is a radio accessory. The top of the case is secured by a flap with a quick release buckle:The base of the case has a double thickness of webbing to reinforce the end:Sadly the shoulder strap is missing from this case, but one of the metal loops to attach the strap remains, sewn with heavy duty stitching to the main case: The aerial case can be seen worn over the shoulder on the official WS38 operator’s card: As can be seen from the card, the case should contain two of the thinnest aerial rods, rather than the one I have but for the price I paid for the set I really can’t complain!
