I found this interesting link. Selmer apparently did stencils early in the piece. This difference being I suppose is that this one does look like a Selmer Model 22. The Selmer logo though is quite a bit different than what became usual.

After you quote my old website, I appear.
First, I'm going to give some props to Mark over at saxquest.com/saxophone.org. He did more research on the pre-Modele 22 horns and was able to confirm that some of them were designed by Selmer. However, I can't find the *&%$!! page, ATM. You can search
https://saxophone.org. I know it's there, someplace.
Second, I have the benefit of a bunch more years of research since I sold saxpics.com. I can now identify some of the stencils,
like this one. That's an AE Sax-made horn. And Mark at saxophone.org had already mentioned that. The octave key mech was either copied from Dolnet or Dolnet copied from Sax. In either case, I've been able to
break down all the AE Sax horns and they were in a few "series".
In any case, is this horn in the eBay ad a Selmer? I definitely don't think so. AE Sax? I've never seen an AE Sax instrument with right-hand bell keys. Couesnon? Other than the very interesting
Système Dupaquier models, Couesnon didn't switch to right-hand-bell-keys until after 1935 or so. Also, remember that Selmer's first horn with right-side bell keys was the Balanced Action.
So. I have a strong opinion on what it
isn't. I don't have a strong opinion on what
it is. It has a bit of a look of an HN White King. The left hand G#/C#/B/Bb looks a little like Couesnon. No, I don't think the Selmer stamp is original, either. Selmer says on their website when they switched logos switched logos: 1926. IMO, the Selmer design looks like a slow evolution until the Balanced Action, which was a radical redesign. This ebay horn doesn't look much like a Modele 28 or New Largebore.
