Re: Help 'tuning' Trapshoot wallhanger receiver board (1975)

Hi John,

It's after the holidays, and I got a bit of spare cash.

Thought I would check to see if you would still be interested in selling the
NOS Trapshoot receiver board.

I'm tired of looking at the wire hanging out the back of the thing!

If so, LMK the total with shipping to Appleton, WI.

Thanks a bunch - hope your holidays were fun!
