Robert Hoyt
2379 Mt. Hope Road
Fairfield, PA. 17320-9759
Phone is (717) 642-6696

I've been told to call him first thing in the morning and let it ring. It was so many years (decades) ago, that I don't have any personal memory of my call, but I don't recall him being hard to reach. I see on line, however, that he can be. Phone appears to be the only way.

I think Lee Shaver in Missouri could be another (definitely capable). He gets pretty swamped (bad pun there), but his number is (417) 682-3330 in Lamar, MO.

Not sure if either of these are close to you.
