Help Identify

[Barry Churcher]

Can anyone help with the identification of this 39931 radio mount? Thanks very much.

Hi Barry,

Post-WW2 and it's the base section of Carriers, Set, No.73. (From WO12211.)

Z2/ZA 39930 CARRIERS, SET, No.73
Z2/ZA 39931 BASES, CARRIER 24.3/16-in. x 9.3/4-in. No.1
Z1/ZA.39126 SHOCK ABSORBERS, BRIDGE, 4.3/8 in. x 1.3/8 in. x 1.1/2 in. No.5 (Qty 6).
Z1/ZA 39932 TOP-PLATES, CARRIERS, SET, 24.5/8 in. x 9.21/32 in. No.1

It looks as though it would take a WS19 and supply unit, using the very long strap from Carrier No.25, but I don't recognise the hole pattern(s) on the top plate - maybe Larkspur-era control and power boxes?

Best regards,
Chris.

Thanks very much for the reply Chris. Now I know what it is and what I can use it for.
Cheers

What the complete unit looks like - I have no idea what goes on the top deck!



Best regards,
Chris.

Barry,

I shared your pictures on Facebook to a WW2 Wireless group. One of the group members shared this picture saying it was to hold a high power set.

Hmmm...

There's also a "Carrier, Set, No.84" but that has a later VAOS number - up in the 40,000s, which has a plain, undrilled top. (Bear in mind these will be draughtsman's impressions from the (presumably) original drawings and may bear little resemblance to what was eventually issued for service.)

The hole patterns in the top deck of the '73 bear little resemblance to anything sensible - I suspect it's an "artist's impression" of the earlier top plate, with no measurements, as that would allow LH or RH fits for Variometer, Aerial Base, and Control Unit, plus (possibly) other stuff.

In the drawing, the three holes for the variometer are much too close to the LH edge of the top plate, and the Aerial Base No.8 or 10 should be in the middle, with a Control Unit No.2 to the right of that. (The arrangement can be 'flipped' for a "Right Hand Side" setup, where you have two sets in the back of a vehicle.)

The Facebook photograph is of a "barefoot" WS19 since it has the standard variometer rather than the Tuning Inductance - and you'll let the Magic Smoke out if you try a variometer with the RF Amplifier No.2!

Best regards,
Chris.

Thank you Chris and Jordan for all your efforts. The photos sure make it much easier to see how it was set up. The turnbuckle was confusing me as to how it worked because I thought it somehow hooked into the radio and I don't have the top tray.
Cheers
