Curious to know if all Favorites with the "square-cut" receiver have steel buttplates, as does mine (#7455). My suspicion is aroused because the one on mine doesn't fit well--stands proud of the wood at toe & heel, though there's no evidence the stock has been altered. Grant doesn't indicate (that I can find) when the transition to the hard-rubber plate was made, but I've assumed it probably accompanied the change to the radius-cut receiver.
On page 7 of Boys' Rifles Grant expresses the opinion that the transition to the hard rubber buttplate happened in 1898 or 1899, based on comparison of parts lists.
Compared to mine, yours is a very low serial number, suggesting that they very well may have started at zero, and thus produced a lot more than I ever imagined possible. (Learn something every day!)
BTW update on mine - Wisner's delivered the replacement mainspring, and oh, man is it too heavy! Thickness .058" whereas the original was .010 thinner! I've narrowed it on a belt-sander to where I can cock the hammer with only one hand. Fired one round of Navy Arms ammo, which split longways from rim to mouth!
Because the breechblock is tight against the breech face there wasn't any noticeable gas leakage, though. Gotta mow the grass on the range before I shoot any more.....grass is obscuring the target.
