BOSS .410 OVER-UNDER, SIDELOCK EJECTOR, SINGLE TRIGGER GAME GUN WITH CASE

BOSS .410 OVER-UNDER, SIDELOCK EJECTOR, SINGLE TRIGGER GAME GUN WITH CASE

I already put up a post about these incredible Boss shotguns. Now that the auctioneer has posted a complete set of pics and a full description for each one, I wanted to mention them again. They are that stunning — and rare.

.410 Boss & Co. Side-by-Side Shotgun

.410 Boss & Co. Over-Under Shotgun

These shotguns are best-quality, London-made sidelock .410s by Boss & Co: a side-by-side and an over under. Ordered in the 1950s, they are in incredible original condition. Pre-auction estimates put their value at $135,000+ a piece. The final hammer price will probably be much higher – especially for the O/U. Last spring, a set of 28 gauge Bosses in similar condition came up at Julia’s. The final prices for those 28g guns were $138,000 for the SxS and $207,000 for the O/U.
