[Milsurplus] B-17 Radio Questions

[Floyd Petri]

When I was a kid there were WW II silver aluminum receivers and transmitters 
every where. I can't remember if they were called Command Sets, Arc-5 sets, 
BC-459s or SCR-274-N sets. Of course I did not want any back then.

What is the chance of getting a couple in mint or near mint conditon or at 
least excellent unaltered condition for my
WW II collection? What would be a fair price for them?

What manual name or TM number would cover the system in a B-17? I would like 
to see what each individual component is and what it would take to complete 
an original radio operator's position in a B-17 including racks and 
connecting cables. At the moment I can't remember how a pair of headphones 
would connect to one of them??? I know hams back in the 50s would convert 
them and they had a jack installed on the front.

If anyone has any for sale please contact me. I prefer the aluminum Army 
ones as they seem to be cheaper. Thanks.
