  1. Yes, they're the later (tropicalised) version of the HT1 dynamotor for the British WS19 power unit. Certainly of interest to me.:-D Chris.
  2. (That ground spike does not look original - more an example of the welder's art, the originals were cast/forged.) The British mast was the "34-ft steel vertical aerial" and came in a big canvas bag with shoulder strap. It's made up of 3-ft Aerial Rods 'D', an adapter and some Aerial Rods 'F'. Somewhat flimsy and tricky to erect without bending/breaking the rods. Also (apparently) prone to falling down if any of the guy ropes got shot away. :-D There's a 'kit layout' of that mast on Keith's WS22 page, here: http://www.royalsignals.org.uk/photos/ws22/index.htm It remained in serv
  3. I just noticed the 'A.P.' part number. "Admiralty Pattern" so probably off something very substantial! Also, 60 volts at 15mA is 0.9 Watts, so your series resistor will get quite warm and needs to be rated at 1 Watt or more. Chris. (G8KGS)
  4. Er, how big is the battery, because 15mA is quite a considerable current drain for a meter, and you should be able to get something far more sensitive than that without too much difficulty. (500 microamps (0.5 mA) was common for panel meters during WW2, and modern test meters are usually a tenth of that.) Chris (G8KGS)
  5. Of limited (close to zero) use without the "Big Bag Of Connectors (and connecting cables)[TM]", unfortunately. Chris.
  6. Probably the general purpose "Aerial, Vertical, 34-ft, Steel" consisting of a canvas bag and a load of Aerial Rods 'D' plus ancillaries. (It could be used to make 2 x 12-ft masts if required, an 18-ft mast or a 34-ft vertical aerial.) See Keith's WS22 page (towards the bottom): http://www.royalsignals.org.uk/photos/ws22/index.htm The "aerial wire" could be any of the ready-made aerials, the 100-ft No.5 (with links to allow pre-set lengths), an 'all-wave' longwire, or packets of copper wire and loose insulators for making up your own aerial to suit requirements. The SLU had speciali
  7. Those are standard meters for the period. The ammeter should be simple to find (I may have one in the bits box), but the voltmeter less easy - it may be necessary to transfer the scale plate to another meter. Both meters are the 'moving coil' type, so are intended for DC. Is the generator off a searchlight or something like that? (Current is a bit low for a welding set.) Regards, Chris.
  8. Wireless for the Warrior Volume 2 has them listed in Appendix 9, with a small drawing of a wooden cased battery. Someone recently posted a photograph to the WS19 group asking for identification of a battery box, and that was a pressed-steel 6V 170AH dated 1945, so they are presumably late/post WW2 manufacture. (The ones I have are dated in the 1950s, I think.) Be warned: they weigh 99 pounds unfilled so are easily a hundredweight apiece when in service.:wow: Chris.
  9. ALL WW2 respirator filters contained asbestos. That particular bag is for the "Service" respirator, with the oval can on the end of a hose to the mask. The filter can contains blue asbestos (crocidolite), which is the worst kind. The other common respirators, e.g. the "Civilian Duty" variety with a substantial rubber mask that had the filter canister fitted to the front, contained white asbestos (chrysotile), which is somewhat less hazardous[1]. The civilian (thin rubber) masks used substantially the same filter canister as the civilian duty type. A further caution: some respirator
  10. 1) It's a still, for producing distilled water for topping up batteries. 3) Charging sets (engine driven), I assume, and other electrical equipment. (There's a separate trailer for radio kit.) 4) The two (wooden cased) 6-volt batteries stowed underneath provide a 12V DC supply, they'd use a generator for anything requiring 110 0r 240 volt AC mains. Chris. (Memo to self: read all the way to the end of the thread before replying to a question. That way you look less of an eedjit.)
  11. Ah, very interesting and helpful, thanks to all. (Obviously I need to read some more recent manuals.) :-D Chris. (Only just starting to branch out into 1950s radio - I seem to have gone straight from WW2 to Clansman.)
  12. Dark red coach from "Ham travel" (I think, since i've been up since 0400 again), I think it runs at 40 minutes past the hour from the station (it has to reverse into the station approach road), and leaves about 10 minutes after the train arrives (so as to allow people to spot it and get on). It'll be parked in the only place it'll fit: left hand side of the station approach road as you come out of the booking office. Last trip from the Hop Farm to PDW is at 1800. If it's still hourly and you've just missed it, a taxi fare is around £7, and I used Kent Cars (01892 832285) on Tuesday (nu
  13. Shuttle-bus to Paddock Wood runs hourly (not half-hourly as stated), damn-all in the way of signage, and it leaves from the station entrance rather then the industrial estate on the "out of London" side of the track. They've replaced the old footbridge and there's now a passenger lift. Chris. (Missed the coach due to going straight to the old pickup point, missed the early trains from Birmingham because the misbegotten bus disservice failed to run the 0521 to the station so had to wait another 4 hours 20 minutes for 'Off Peak" to restart. (muttergrumblesnarl) a 20-hour day and I'm doi
  14. I think the changeover between FFW and FFR coincided with the roll-out of the "New Range" of radio equipment to the army as a whole (under the project name "Larkspur") after the RAC and RA had been equipped with it. The WW2 and early postwar sets were all designated "Wireless Set" (or in the case of separate transmitters, "Wireless Sender"), e.g. WS 19, WS31, WS88, (WS 12, 33 & 53 were all Senders with a separate receiver, such as the R107, R209, AR88). The "New Range" were "Station Radio" instead, e.g. SR C1I, C42, C45, and Transmitter "T D11" or Receiver "R 230", etc. So I think
