Did Flatiron make any oval hole mandos? I'd be interested in a Flatiron A and I've got a Weber Bitterroot F to trade.
Dale, the only oval Flatirons are the pancake, Army/Navy style, that are much discussed and favored by their owners. Keep your eyes peeled, if your interested, as they do come up for sale every now and then on the classifieds, on ebay and elsewhere.
Dale, I think INTERMOUNTAIN GUITAR & BANJO, Salt Lake City, Utah have an A5. Premium priced, but you could try to make a reasonable offer.
