Today someone is offering six old Vega resonators on the eBay. In case you're interested, just search on Vega Banjo and they'll show up. One piece, two piece and pie plate backs.
Dang, at $99 a pop, too. No flanges, though.
I have a 4-piece flange set that would work with any of those — probably more appropriate for that circa 1930 2-piece back than the '20s pie-plates that scream for 28 piece individual flange sets.
Hopefully, Paul will chime in and tell us the story on these.
