This shotgun is an W. & C. Scott Excellentia Triplex, Scott’s B-grade hammerless double and one step down from The Premier, their best quality double. (Scott also made at least two back-action “Premier Extra Specials” during this time, but I don’t think that grade was ever officially offered by the company.) The color-case hardening is fantastic and I love the acorns chiseled on the locks and action. The brown on the bbls is great, too and so is the blueing (note: Those bbls were browned originally and never finished in black & white like some people believe). Check out the shape of the stock, too. Nobody makes stocks like that anymore.
Scott made back-action Excellentia’s from 1884 to 1888. I think this one was made in 1887. It’s on a Scott & Baker patent action and it has Scott & Baker patent gas checks, a version of Scott’s patent Triplex Lever Grip and Crystal Cocked Indicators and Needham & Hinton-patent Block Safety (intercepting sears) on the locks. What a gun.
If you have a Scott shotgun and are looking to find out more about it or sell it, please let me know. I would be happy to help you with it.
