I think you are seeing another auction since the original has expired. Ebay likes to send you to another similar auction, thus the 28M photos.This looks like a garden-variety 28M ( Constellation) to me. It has replacement key guards because the stock, plastic key guard has obviously gone bad. If you google "Conn Constellation 28m alto saxophone", you should find photos.
Then maybe interesting to read thisThis sax is really a stencil since it is a Vito Kenosha engraved as a Conn. Probably not even engraved by Conn as the shooting star engraving is different than what was on the older pan American type 14m or later Vito type 50m. It is sort of a 50m prototype in that it looks to be more like a Vito with the vertical side F sharp key and Vito O-ring neck socket. The F sharp would be changed as Conn evolved it into the Arizona/Mexico shooting star alto. The O ring neck socket doesn’t show up on any other Shooting Stars as far as I know.
I've not had that happen before, but now that someone has posted photos of the horn in question, I can see we're talking about a very different axe.I think you are seeing another auction since the original has expired. Ebay likes to send you to another similar auction, thus the 28M photos.
