That is one discovery I wish I wouldnt have discovered. That has to be THE most annoying key buzzer I've ever heard, lol. I had a couple of cool discoveries.
Numbers matching (found out the day after I bought it)
Both broadcast sheets. (found winter after I bought it)
I have a '70 console, which I should make money by selling and buying the correct one.
Really the only other thing I would like to find is the previous owner/owners.
