They can be identified by the 6.5 or 6.6 stamp on the back which this has. Yes this is the very first run of soldered tone holes but they all seal very well and that's not an issue at all with this horn. Jazz players love Keilwerth's because they are free blowing, have fantastic lows and are the perfect Tenor in a big band.
Do you want to be heard? Play a Conn 10M or a Keilwerth! Clarence Clemons rest his soul switched from a King Super 20 to a SX90R and played 2,500 shows with it and I believe his son now plays the same horn.
If you want to really hear these in action today check out monster player Dayna Stephens and his quartet. In total, it has maybe. This horn is literally in mint condition in the original case and MPC. The pads all seal perfectly and the horn will stack up to any Selmer BA or SBA.
