Based on the first photo in the hangar, I believe I remember it belonging to a Club member...found it... Dennis_Ozment in Quincy, IL!
As far as the engine, it's not really that close to TBO, especially with a TOP 480 hrs. ago. At the rates most of us fly, around 100 hrs. a year, I could easily see getting another 4-5 years out of the engine before you'd even have to think about an overhaul but, that's just me. It sure looks like a nice one, though.
