Kevin.

i will take some pics for u ........ the frame is steel.. the aust one..the uk made frame is alu i think

[Mike K]

This may help. this frame is steel , the magnet sticks to it . I think the UK frame is aluminium but not 100% sure. Dont know about Canadian production Mike

[kevin powles]

Mike, it appears The Canadian 11 set tray is All Alluminum, I have talked to few guys in Canada who have confirmed this. Now I have a delima to make an Australian version or Canadaian,? I have a volunteer worker at the Royal Signals museum sending me some pics of one in a glass case there, he doesn't know the country if manufacture but he is going to find out, if British we might be able to confirm the British manufacture method for the tray. Here a pic of it.

The Blandford example is a E.K.Cole UK built set . Some friends sent me a movie of the museum years ago... the 11 set on display is in a glass case , this is because its rare as hens teeth . Its a mystery why only a handful of these survived ......... many were lost by the BEF but not 18,000 which is the production total , so Lou Meulstee says . Apparently the Germans printed a manual for the 11 set , they had captured many of the sets .

The Aust. version was a disaster in the tropics .. the cotton insulation was a great home for fungal growths BTW the Aust. sets have a date scribbled in pencil on the back of the main tuning dial, Ive seen this on quite a few sets . The production ran from 42 into early 1943

I have used a 11 set on the ham 40 metre band , once was enough .

Hi Mike, Thanks for that, great info you have and interesting in sights. Hope the guy at the museum comes through with some pics but he did sound vague on the phone and in his words "extremely busy" doing what I don't know, things most likely move at a fast pace in these museums .

The British one will be steel.

Britain had a steel industry (also Dunlop and similar rubber companies), Canada had/has shedloads (technical term) of hydroelectric power, aluminium smelters (due to cheap electricity) and forests. This caused interesting variations in the materials used for WW2 hardware. British made Telephone Sets D Mk. V have steel cases, Canadian ones are Aluminium. The British made Aerial Base No.8, Mounting No.3 is a thick rubber moulding (later ones were a steel donut with rubber gaskets), the Canadian one is plywood with cork gaskets. The "Piece, Packing" for the WS19 variometer can be Bakelite (UK), Rubber or wooden (Canadian), pressed steel (US) or cast aluminium (post-WW2 Italian).

I'd imagine the Australian carrier is also steel, since they made the WS19 aerial mount N0.3 (the very tall one) out of steel with a steel spring where everyone else used rubber and aluminium.

It's all down to availability of materials at the time.

Gina,
Do you still want a plug casting?, I am getting one made for Philip. I don't need one so the guy is only making one, but if you need one it will bring the price down. I can do all the machining and hole tapping. It will come without brass inserts but I have a drawing for making these.

The 2-pin plugs should not be that difficult to find, since they were a "multi purpose part" used on a variety of sets (WS11, WS19 RF amplifier, R107, DC-AC converter for the Typex machine, etc.) and were still current issue in the Larkspur era.

The 3-pin connectors are more difficult, despite being used on the R107 (muting plug) and a lot of Line kit (mostly carrier telephone stuff). (Anyone with an R107 needs one of these to blank off the muting connector which has 250 volts on the exposed pins!)

Some Dutch eBay sellers had the 2-pin version as WS19HP power cables, and they may still be around somewhere.

The moulded replacements for the "domino" sockets are a work of art, but it would be much better if the contacts could be include at moulding time - they're only a brass pin with a central hole (tapped at one end) and a groove with knurled bottom to retain them in the body. I don't know how complex the moulds are, but it should be possible to incorporate the contacts before filling the mould.

OK, on the assumption it's the same as the WS19HP one, I have a NOS example and will calculate you a postage cost tomorrow (I hope).

Hi Kevin if Chris is good to send me one then I am ok .

Hey Chris send me a Pm as to costs... do you have a pay pal ??
