How To: 1944 Chev HUW restoration

[Bruce Parker (RIP)]

So here's a question for Mr. Bergeron and Mr. Baker, and hopefully Chris (da signals goo-roo) Suslowicz:

All three lightweight CMP wireless trucks, C-15A WIRE-5 with the 2K1 body, C-15A WIRE-3 with a modified GS body and C-8A WIRE-1/WIRE-2 (HUW) based on the Chev Heavy Utility have five seats, two in the cab for a driver and co-driver and three in the back, one facing the wireless table and two others.

I have always assumed this meant a crew of five. But then I looked at the space required for five signalers, their kit, rations, greatcoats and see a problem. All that shi-et won't fit!! Plus, it really doesn't take five people to set up a wireless station and I can't see the army condoning the driver and co-driver twiddling their thumbs while the signalers set up their bits.

So my question is this...did the crew consist of five members or was it less and some of the crew occupied either the cab or rear seats as needed? I half doubt this because the rear seats do not appear to offer any benefit other than a place to seat one's arse when on the move so functionality may not be the reason for them.

What was the compliment for these wireless trucks?
