I've seen Syracuse Lefevers advertised and misidentified as Nitro Specials. I've bought several 16 and 20 ga. Syracuse Lefevers from people who are FFL Gun Dealers, that were advertised as being 12 ga. So sometimes dealing with an uninformed seller can work in your favor.

Anyway, thanks again to Ed for being kind enough to pass along a possible deal.
