Here's a Stevens Model 620A-- the streamlined version of the 520 with the same Browning bank-vault sliding-groove takedown mechanism. Barrel is 28 inches and was described to me as modified. The gun has been refinished and the metal is a nice even gray-patina color. Stock and forend show use, not abuse. Bore is excellent. Manufactured between 1940 and 1955. No serial as was often the case in those days. Runs like you would expect a Browning pump to run -- which is very well. Asking $300 and $35 shipping to your C&R or your FFL dealer.
