I have also seen them with CPR on the top, so it looks like pyrene would custom make them for companies or departments.

Don't kid yourself, they were marked because if they found one in your kitchen it was proof you pilfered it from your employer.

I find they're like those 2 gal. POL cans, buy them when you find them because you need several for each vehicle (standard CMPs luckily only one).

Started installing antennas . One receive , one send as per no 19 HP set instructions . Two No 8 bases on two opposite chimneys as to avoid interference as much as possible .

[Robert Bergeron]

Because of the lack of space i decided to install horizontal aerials temporarily at least till i move the truck outside . Antennae set , ground set , batteries set , control box set : Next , a first reception test on the No 19 set in the next few days ....Will keep you posted .

Removed the covers on the antennae chimneys . Under the top covers i found bolt hole patterns for the No 9 base to the left and the No 8 base to the right . On the center chimney cover i found this peculiar pattern of 4 1/2 in X 4 1/2 in . What antenna base uses that bolt pattern ? Maybe post-war use with other radios ?

Same center plate

4 holes on 4.5" square are (I think) for Aerial Base No.3, which you can't feed from underneath - it is top-feed only, usually via a 'black-out' box and feed-through insulator on the end wall of the "house-type" body. (Hence the solid plate on the existing 'chimney'.)

If you needed a 'through the base' feed for a high-power set, there was a Tufnol plate that replaced the steel one with a large central hole and 6 holes in a hexagon pattern that match Insulator, W/T 'H' (a large ceramic mushroom type) that formed part of "Aerial Lead-in No.16" (It had a Base No.3 on a plate fitted to the Insulator 'H' and the flexible rubber dome was bypassed by braid straps to the plate.)

For insulators on a frame at the front of the 'house' body there was an adapter plate (ZA.21283) with 10 studs - 4 to fit the support frame and 6 for the insulator assembly.

I can probably supply photographs if required, but it means fighting my way past piles of stuff to find the items concerned.

Both bases take Aerial Rods 'D' (the 34-ft steel vertical aerial), and there was a metal 'cage' to support the weight of tall aerials and prevent the Base No.3 rubber dome collapsing. It was later replaced by Aerial Base No.25 which had a metal socket for the aerial rods and did away with the rubber Base No.3 altogether - it just used the Insulator 'H'.

Best regards,
Chris.
