Along with the 103, this is one of Alexander’s flagship models. It is a Knopf-type instrument. It features a bell that is slightly wider than the 103’s,
providing a more comfortable playing experience. It also delivers a natural, well-defined tone that extends all the way down to the low register.

[Comment from the Repair Technician]
After disassembly and cleaning, the rotary valves have been adjusted.
This is a used 1103, which rarely comes up for sale.
If you miss this opportunity, I think it will be difficult to acquire one.
Please consider this instrument!
