Man, the nickel on your engine is really nice, the paint on the base too (re-painted?)! Runs / sounds great. That leak on the sight glass is a easy fix, just need some o-rings ;-)
I have a turbine, though the nickel isn't near as nice. Not sure I'd be able to offer you a fair price, since I am not itching for it. I passed up one from Carl's collection being sold by SlowJoey (been meaning to ask him what it finally sold for as it was a buy no / offer listing).
Thank you for thinking of me!! <3
