Hey Frets,
Yea the Cooperage is still there and going strong, although the last time I was there was a few years ago for some friends retirement party.
I think you should build your Grandfathers 27, a wingman with #11 on it. If you need it I'll make you a good deal on a Royal P51 kit

.
Anyway, great story! You mentioned military service earlier, did you become an AF pilot also?
