Manufactured in 1971 in special order 257 Roberts caliber. Features gold filled (faded) scroll engraving on the floor plate and trigger guard. Includes an August 19, 1976 dated letter from Browning stating "Your Browning Safari Grade Rifle, serial #62438171[sic], was made to special order for a customer. This is not a production model but at the time we were manufacturing the Bolt Action, we had a policy of supplying almost any caliber desired by the individual customer. This is no longer done, however, on our centerfire rifles." Hand written note on the letter says "6 made". Provenance: The Dr. Robert Azar Collection
