I have been playing a Kanstul made Burbank trumpet for the past 15 years. It is a great horn that really has an exceptional sound, I have not been able to find out much about Kanstul made Burbank's on the web. I believe these horns were made by Zig Kanstul in the Anaheim plant even though my horn is engraved with the old Benge address in Burbank. According to info I received from Kanstul, my trumpet is a 3MLP model with a .464 bore and a 4 3/4" bell made in April 1986. It is all silver plated. Does anyone know anything about these horns? Are they considered quality trumpets? From the great valve response and sound I get from mine, my guess is they are. I have yet to see one listed on eBay or other sites, so I'm not sure what the going rate would be for one of these horns in excellent condition. Does anyone know?
