Dave, I'm not sure how much info you have on Washington Everson, but in case I can add something, here's what I have. Everson was born in Pennsylvania in 1811. Soon after completing his apprenticeship, he moved to Louisville, Kentucky where he is first documented as a journeyman working for Louisville's most prominent gunsmith at the time, Moses Dickson. He showed up in the 1860 and 1870 censuses in Dearborn County, Indiana where he was listed as a gunsmith. His son John was born in Kentucky and 22 years old in 1860. Unfortunately, I don't have census data on him for the intervening years. I think some people think his first name was "William," but in the Louisville City Directory of 1838-1839 the first name is clearly "Washington."
I do not have photos of a Washington Everson rifle for my ongoing Kentucky work and records, and I like the look of your rifle. It is very much in the style of a Moses Dickson rifle, back-action lock and all, of the late 1830s. Is there any chance you could re-shoot a few (4) pictures of your rifle for me? If so, I would greatly appreciate getting: 1) a good full length shot, 2) the standard half-length shot of the front showing out to about 10" past the lock, 3) standard half-length of the back side, and 4) shot of the barrel signature. I have found I can get very good pictures if I lay the gun on a concrete driveway (carefully) outside but in the shade...with the barrel pointing in the direction of the unseen sun. The concrete gives a solid, off-white background that is easy to photoshop out later on.
Thanks for posting your rifle. I really enjoy seeing a new rifle from KY, and particularly when I haven't seen an example of that maker's work. Would you mind posting the barrel length, bore size (approximately) and tang length...and if one or two screws in the tang? Thanks, Shelby Gallien
