Marks 21
That gun appears to be the SAC Grade A gun recently posted for sale on Gun International. Based on screw slot condition, this gun hasn't been molested, and all finishes appear to be original with the exception of stock wood; which appears to have been refinished and recheckered, and of course the pad is a recent addition. The features on this gun would indicate production in the 1902/1903 period (what I've described as the "2nd Model"); and it exhibits all the cataloged features of the SAC Grade A gun with the exception of optional Krupp Steel barrels. This gun was cataloged at $75 retail during this period, and represented a lot of value for a gun of this quality at that price point. That gun has lots of life remaining; and I hope you have ample opportunity to enjoy using this piece with great effect in the field.
