... and sopranos from the same era ...
Note that most baris from this era only have the left side Plexiglas keyguard, but sheet metal right-side guards.
I have seen a couple that do have the right side "angel wing," but that's uncommon.

You might notice that I'm posting a few horns in here that are actively for sale.
I'm doing that for a few folks that have been long-time contributors here.
The standard disclaimer applies: they're not my horns, I don't claim they're good or they're in perfect shape, etc.

If you want to list your horn, e-mail me at thesaxinfo-at-gmail.com and we might be able to work something out.
