Quote "THIS IS A RARE HUSQVARNA 12 GAUGE MODEL 51 HAMMER GUN. SERIAL #94XXX, MADE AROUND 1916." Nonsense!! About 11.000 were made in 12 gauge and about 3.000 in 16 gauge. Made 1911 to 1947. Most common toplever, backaction locks double produced by Husqvarna, mostly because was least expensive (no engraving, etching, etc).
Round body? NAA -- just rounded lockupbox, just like nearly all older Husqvarnas. Is much nicer to carry than wide lockupboxes on A&D receivers.
I have seen several of these "refurbished" M51s -- they are all quite ugly -- don't know who did them. IF steel not ruined, can polish off "case colors" and have nice "French Grey" or "coinfinish".
Excellent handling hammer double, especially with 75-85 cm barrels in 16-gauge. Usually has stock with "modern" dimensions, not those dog-leg, droopy stocks like on old Parkers, etc. Not very best handling of these older top-lever Husqvarnas, at least for me. Models 48 and 52 in 16 gauge give me highest scores on clays and live birds, right up there with my favorite Sauer hammerdouble and Merkel-made kombi. Maybe not to be surprised -- Husqvarna had good working relationship with Sauer re sidelocks and lockupboxes.
