Pan American 64H Champion
Date: 1930's. Owned by Andreas Kolpatzik.
The silver finish with gold wash bell (if original) is unusual for the 1930's; most instruments finished that way are from the 1930's. The 1938 Pan American brochure calls it "Finish 2".
What Pan American said in 1938:
Air-tight, carefully ground "Slik-Slide" and rich, mellow tone. Built in Bb, medium bore, 7" bell. Internal mouthpipe! Note balancer and slide lock.
