[Dreadfulnaught]

Thought I had seen it all but I’ve never seen a Hayden guitar. It looks kind of Bay Stateish but the truncated pyramid bridge was used by the Larsen Brothers (in fairness, others used it also). I’d look for other brand names with a similar stamp in an oval. May have been made by the same people. I’ve seen that before, and I’ll try to remember where.....
I would feel comfortable saying that it was a slothead, and a lot were squared off like Martin.
This is great, like exploring King Tut’s Tomb without getting dirty.
