[ARC5] Very Scarce Piece BC-611 BC-721

[David Stinson]

As soon as I get a chance, I'll reference some data
I've found on this.
Summary- the early Wacos used a wire line to the tug
and tacked-into the tug's interphone.  The glider pilots
used the J-37/AIA-1A jack box for their mike/headphone
connnections, at least in some gliders ("Wacos" were built by
several makers and had differences).
Here's the rusted remains of a J-37 box on a recovered
Waco frame:

One of those sets I'd hopedto build one day (dream dream dream) ;-)73 Dave S.
