This is a very interesting horn. Serial number 23xxx, an earlier Balanced Action, it is set up with metal resonators and is in pretty good playing condition. The pads could at least do with a bit of reseating and adjusting. I have not looked deeply into it yet. It has a wonderful crisp and rich response.
The unique thing about this horn (besides its sound) is that it appears to have been made without engraving and then sent to the Selmer factory to be relacquered and engraved with the current engraving of the late 1940’s-early 1950’s (SBA) Super Action style. It is quite obvious to me that this had to have been done at the factory. The lacquer color is also appropriate to the SBA time period. The horn does not appear to have been buffed and there is no evidence (in any way) of prior engraving under the SBA pattern, so it is just very unusual and interesting.
This horn is beautiful and just has a phenomenal sound that will never be recreated. It is a joy to play.
