An excellent pair of rifles, one quite early, the other later

The earlier Stephen Grant, with higher hammers, non-rebounding locks with "stalking" safeties and the lovely percussion style fences is particularly attractive, with nice rose and scroll engraving showing the patina of age

The .577 3" is probably the most desirable calibre for a Black Powder double. My own .577 3" is much plainer

Good luck shooting them
