11 Set stuff

The Morris box is quite a bit smaller than the CMP one. The CMPs put the second set of batteries to the right of the radio with the remotes and stuff. They also have those lockers built onto the front of the box. What are those two units clamped down behind the set on the Morris?

Interesting! They look very much like a pair of the "Static Battery Boxes" used with the Wireless Set No.18. This was a moulded bakelite case that took a selection of dry cells and batteries (2 x 60 volt, 3 x 12 volt (making 156 volts tapped at 12V for HT and grid bias) and either 2 x 1.5 volt "Cells Dry, O" in series, or 8 "Cells, Dry, X" in series parallel to provide 3 volts for the valve filaments. This pack had a 50 hour usable life. I'm fairly certain that's what they are, as the photo shows the case screws on the front and the web carrying strap on the side. I have the bottom half of two of these cases (stripped) - they were emptied out, the lids and fittings discarded, and a drawer knob attached for use as a parts storage system. :-(> I want a complete one for my 18 set, but no luck so far.

Sorry Chris but I meant the truck box.
Like the whole body on the truck that everything is mounted in!
From the cab to the endgate.

Er, which truck box?

The two square cases directly behind the WS11 in that photo (at top right) are almost certainly WS18 static battery boxes. The 4 wooden-cased accumulators clamped to the floor in front of the set are for the WS11. I don't see anything else you could be referring to in that photograph?

Chris is correct

The WS 11 uk version had provision for running from dry batteries . Those are batteries behind the set . The UK manual mentions the dry batteries . The Aust. set manual does nor list dry batteries so they must have dropped the option .

Would any of those dry batteries have survived ?

BTW the Morris PU had a auxillary generator for charging the wireless batteries, the gene was mounted next to the gearbox, driven by a PTO and pulley .The Canadian setup used the chorehorse .

I have never seen a pic of the charging setup in a Canadian 8 cwt , it would have been interesting as the British units were issued with the Canadian made 8 cwt wireless vehicles

Any pics of the F8 or C8 don't have any of the radio equipment installed. That one pic with the place for the grounding lug for the switchboard is all I have to go by, but it's enough I think.
What set is this aerial mount for? The clamp on top has quite an 11 set look to it. The second image is the 19 set base and this one looks like an earlier version somehow.

OK some confusion about boxes here. I realise now that the Box David is referring to is actually the storage box for antenna and chorehorse etc that the switchboard is mounted too.
Thanks Chris/Mike for the dry cell info. I doubt I'll bother looking for any!

And Mike is right about the other box next to the switchboard, to stow the regulator in. Currently, mine is erroneously inside my dummy switchboard cabinet and will get changed.

David that is a standard WS19 (and others) aerial base. The 11 set base is something far more complicated and elaborate for something like 3/4"? rods.
Again I have a home made version on my PU. There were different variations, the short squat one was fitted to carriers etc. Ron

You have left the light on , your battery will be flat in no time

The base on the far right. I have one of those, I think its a ground base , sits on a spike and accepts the 5/8" rods .

With the 11 set - they used either 5/8" or 7/8" rods . The thin whip type antenna I think was issued with 19 sets

Top pic is Aerial Base No.10 Mk.2 - general purpose HF aerial base for 'F' rods.

Bottom pic is Aerial Base No.8 - original base for the WS19 that was replaced by the No.10 Mk.1 and then the No.10 Mk.2

U.S. and Canadian manufactured sets were still being supplied with Base No.8 when WW2 ended. They are not much good for use on the move because the aerial rod flexing causes the retaining spring to get metal fatigue and either stretch or break, releasing the grip of the base on the rod, which can then fall out and be lost. Hence the No.10 with a butterfly nut clamp. The No.10 Mk.1 has a convex-shaped rubber insulator which met the metal mounting plate at a sharp angle and this was not good for the bond strength. Also it had a two part riveted retaining clamp, as with the Aerial Base No.11 and was complicated to make. The No.10 Mk.2 had the pressed steel clamp with the through bolt that you see (and a built-in terminal for attaching feeder cables for some installations or the spade-ended Aerial, 100-ft, No.5) and the shape of the rubber was modified to be concave where it met the steel plate for better bond strength.

The mounting bracket is for a Jeep, according to the eBay seller. They may be right.
