The Sylvester Alto Saxophone

This saxophone came by way of the late Jay Clark's store, Four Winds Music, in Berkeley by way of Santa Cruz. It appears to be intact. Good thing too, because you'd have to fab any missing part.

Still, it's an interesting piece that looks like the same guy who designed my old Underwood typewriter had a role in its design. The only repair visible is the low C# guard, which was repaired with solder. Also the bottom brace has been punched in slightly into the body, but a slide hammer applied to the post would take care of that in a hurry.

Interesting saxophone. Anyone know about this, beyond that it's covered by US Patent # 2569029, which is stamped on the upper stack's connecting brass piece?

We're listing it as a non-player for practical purposes on eBay. No case or mouthpiece.
