This one is in nearly the same exact configuration as Desmond's as well. It is stamped 4A on one side, and 16 on the other.
Desmond used a 4A 18, which had a slightly larger chamber, but the various chamber sizes on these are actually really close together, not like other brands where there is a major difference between small/medium/large. This piece is also stamped "Rico Products LTD Distributors", and the serial number is 4540. It is in excellent condition.
The tip, table, and rails are perfectly smooth, and original. There is no tooth wear on the beak.
The brass band on the shank is original, not a repair. There are minor scratches and scuffs from normal use, but nothing that affects playability. 065, so it is pretty close.
It works great with a #3 or so reed. If you are going for the'dry martini' tone, this is THE mouthpiece to have!
