11 Set stuff

Good luck with that !

That would make another interesting project Dave."BOXES PRIMARY BATTERY 240 VOLTS" They would nicely fill up the space behind my set. Timber would be easier, but to my mind they look like steel?? The holding frames are simple enough (I have another vague picture of the frames also) Ron

The HT battery was basically the same as the one used by the No 1 set and it looks like it was made of wood. The LT was like the light version used by the No 1 set. Trucks carried two of each. The dimensions are given here.

I'm getting closer!
Here's the same looking battery box as used on the 18 set.
As I thought it's made of wood probably to eliminate the shock hazard.
The cells are wired differently for different voltage.
The Aussie 11 set manual doesn't even mention these batteries.

Bloody good research Dave!

So the way they are stowed behind the set, the dimensions are 15 5/8" (or is it 3/8?) long x 11 1/4" high x 3 3/4" wide.

The screw pattern for the lid of the 18 set box can be seen also by the notches in the case in the line drawing. ie 4 along the top and bottom, 2 down the right hand side and just 1 in the middle on the left. I wonder if the 11 set screws would be the same? Ron

In one of the pictures you can see 4 along the top and the two down the right side and another picture there's the 4 along the bottom so they should be the same. The 18 set box's dimensions are 14 1/2 by 11 1/2 by 4. You get 2 of them with 1/2" space between them for the mounting bolt and that's 29". The 11 set and the 2 power supply units are about 28 1/2" plus the ends of the mounting carrier so that's right.
And here's some hardware to hold the carrying straps.
Now to figure out the LT unit I guess.

So you would go with the dimensions of the 18 set boxes which does look right.

I was confused with the measurements in Table 1 Page 3 which I thought was from an 11 set book.

I've been trolling through my 1939 11 set "signals Training" Pamphlet No 19 Vol 3 but can see no exact measurements. Have you got this one? It's 95 pages plus a load of plates. I can email you a PDF copy if you want it. I also have the Ozzy version from 1943. Ron
