[Boatanchors] National 6 pin coil forms

[Carl]

What I said still holds. The first radio to use that proprietary coil 
form was the AGS followed by the FB-7 and PSK.

Pilot and others used the same pull ring feature but not that unique pin 
configuration.

Since National was making coils long before the AGS,  I seriously doubt 
they wanted to copy someone else.
