Repairman Lee Stofer has a couple interesting horns in his shop, ready to sell. One is an E1 that is a few years old. It is made of .55 metal with the sterling silver bell. This has a main slide trigger, and also a 4th valve locking flap. It comes with what Lee believes is a Yamaha 842 hard case and the Adams soft horn cover. I had a chance to play on this one, and it is a NICE horn! The response is exceptionally good on this horn. There are a few minor dings, but nothing of concern. The bell is scratched/scuffed on the edge (the horn was probably place on its bell routinely). Asking price is $5,000.
