I've asked when the top was done on the 150L.
Here's another one:
66 150F [

The engine was a complete overhaul in 1979 (!!) by Kal Aero in Kalamazoo. 317 Hours in 28 years? From the forum, I don't think I'd be happy to see that.
I hate the colour combo...but it does look clean on the outside and the inside.
