That's what I figured, just couldn't find much info poking around online. I appreciate the help!Papillon is/was a store in NJ somewhere (Hackensack?) that like Courtoue, Bernini, The Clotherie, Louis Boston and others got Italian designers to private-label/white label their products with the haberdasher's name/logo. A pretty common finding. So yeah, it's a private-label Brioni for the Papillon store.
I am the farthest thing from a banjo expert, but have dealt with Andy Hohwald at banjowarehouse.com on some thrifted and auction banjos. Extremely knowledgeable, responsive and very fair purchase prices for the flip. Paid me via PP before I shipped, IIRC.
