 I have two of the units in the attic in their canvas bags.  Basically they
are complete except for some of the external goodies (kite antenna, balloon
antenna, and maybe some other items.  Is there a web site specifically
dealing with the Gibson Girl?

I've been reading a transcript of a trial involving Hoffman Radio work
during WW2.
I'll dig up the links and post in case anyone else has insomnia.

But testimony from Mr Hoffman and from Mr Harmon (chief engineer) has been
interesting.
Hoffman got the chance from Bendix to build the kite antenna for the
SCR-578 Gibson Girl transmitter. The small Hoffman team went 72 hours with
no sleep to deliver the initial quantity to Bendix - they got the contract.
They had to do a fair amount of creative engineering to make a kite that
would float, was lightweight, would break down into a small enough package,
etc. One problem they faced was the specification for thin wall chrome-moly
tubing which was in short supply. They discovered a large stock of stainless
steel tubing and had it redrawn to spec - The stainless tubing was
originally intended for Coco-Cola dispensers :-)
