ours is missing the shelf frame work, Im guessing finding steel 1/4 inch U channel is going to be problematic. :? I also notice there must have been leg or antenna brackets on the back, anyone have a pic of those ?

Paul, Somehow I missed your post from last year. The first BC-191 model was the BC-AA-191. It was built for 12 volt aircraft like the early C-47's and with a BC-224-A was known as SCR-AA-187. In the course of the War, aircraft quickly changed to 24 VDC and the BC-375 and BC-348 (SCR-287) but almost all vehicles except for medium and larger tanks & etc. didn't. So the majority of the BC-191-A and later were used in either vehicular, pack or transportable sets (what later became AN/GRC, AN/VRC, AN/TRC or AN/FRC).

All BC-224's are 12 volt.

The LG-10's were made of hardwood, oak I think. I thought that I had a reverse-engineered drawing but can't lay my hands on it at the moment.

The eight sockets are steel stampings. I'm not sure about the four storage ones but the four operating ones are two-piece, one for the actual tapered socket and one to angle the leg away from the chest. Sheet metal work.

Your correct on all and I've never seen a BC-AA-191 but only have the 10 mcs tuning unit and I think a ant tuning or load for that set , cant remember which its been so long.

As to the LG-10's ....I have the LG 10-A's and they are made of steel. Maybe the earlier ones could have been made of oak.

I made a dimensional drawing of the legs I have and if someone wants a copy they can send me their postal mailing address and I''ll get a copy to them.
They would be a challenge to replicate with the foot pad and the tapered end that fits into bracket on the chest that secures the leg.

I have a couple of pics of the LG-10A leg showing what the leg looks like and the foot pad with the LG-10A stamped into the leg support.

Send me your email address and I'll forward the pics to you.

I guess that I was thinking of the LG-8-A.

I'd like a copy of the drawing.
