If this helps to date your gun? My Henry Atkins sle is sn#895, the original barrels and rib are marked 2 Jermyn St London. According to Boothroyd, Henry Atkins was at this address from 1895 until he moved to 88 Jerymn Street in 1897.This gun does not have bushed firing pins or articulated front trigger. The locks are Stanton as marked,the barrels are marked H.A.The barrels are 30 inches.And as was common in these years, the gun was not stocked to the fences. Bob PS great looking gun, I had been following it for some time at Kirby's site.
