Joe,
Prior to Peter owning the plane it spent a year being leased to a Rapid City, SD flying club I started:

I'm afraid I was responsible for damaging the left wing during a taxi (wing went over a pickup truck's roof), but was repaired.
The guys we leased the plane from were a couple A&Ps who had been doing the maintenance on it for the Spearfish owner - likely your uncle. They eventually purchased the plane from that owner with a plan to start an aircraft rental business. They got sticker shock at the insurance cost and when they heard of my attempt to start a club they offered to lease it, which we accepted. The biggest problem we had was the low useful load and many pilots these days are a bit heavier than days of yore, so went hunting for something with a bigger useful load,
