(Pete) These are modified Amati baritones. The finish is automobile paint. That's not actually a big stretch: the colored enamels used on Conns and Bueschers in the 1920s ("Chroma" finish) is an enamel incredibly similar to this.
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.
