Here is a 15” Sitka/Mahogany model I built. The Sitka came from the old Bellanca Aircraft wing works in my home town. When they closed in the 80’s a guy in town got all these quarter sawn Sitka blanks that were perfect for a small archtop.
In another life the top would have been part of a wing holding a turbocharged Bellanca Super Viking in the air!
I put the Bellanca logo at the 12th fret.
It is a very comfortable size.
