I just aquired a small pile of altos, mostly to use for parts, all Buescher stencils, two of which are Elkharts with a cartoonish engraving of an Elk on the bell with 'Made by Buescher' enscribed beneath. Has anybody had experience with these? When were they made? Are they downgraded Buescher models? Good players? Here's the lowdown: Bell keys are on the left. Front F is present.
Horrible lacquer on both. Perfectly rectangular G# key with no roller. Bill Baldwin The Turning Tide Epub Files. No G# trill key. From looking at pictures, they seem to have the body of a late 1930's Aristocrat but the low B/Bb guard is slightly different, attaching to the body at only one point instead of two. I'm considering swapping parts to get one working to see how it plays, but I thought I'd see if anyone had experience with these first.
Buescher acquired the Elhart Band Instrument Company (similar to Conn's purchase of Pan American and Martin's of Indiana) and retained the name (with the 'Built by Buescher' tag) for its second line of horns -- student or intermediate quality depending on individual experience. Earlier horns were either Buescher or Martin stencils.
