J&W TOLLEY was one of several British gunmakers that exhibited  at the Philadelphia International Exhibition of 1876' For may years I owned  Tolley gun #1749 a 10g ball and shotgun made or this exhibition, This remarkable gun was engraved with scenes reflecting life on the frontier. Including on one lock plate, a settler with lasso in pursuit of wild horses on the other a mounted first nation sportsman  hunting elk .On the underside of the action a frontiers man is pictured in hand to hand combat with a first nation  warrior. Truly a unique and unusual gun.  I consider this gun to be perhaps the most interesting find in 60 plus years of collecting. I am in my 90th years but this gun remains  fresh in my memory!
