Here's the link to the Davis kit
Fusil Fin The flaws with the Touchmark are small but stand out when you see a correct version. First off a Tulle should have a 44" or longer Barrel. Second the side plate has that curly-que was found only on some of the high end fine guns. The wood on the Centermarks is Maple, and the Tulle's were walnut stocked. The fore end needs more much wood removed, they were barely 1/16" thick. Don't know about their kits but the metal work is supposed to be in the white, and not browned. And lastly the lock needs some file work to make it more correct. As reference I would suggest "The Fusil de Tulle in New France 1691-1741" by Russel Bouchard, published by Museum Restoration Service, and "Colonial Frontier Guns" by T.M. Hamilton. Can't change the stock or barrel length on mine, but I can remove the brown, and restain the stock very dark, after wood removal. If you were to get the Davis kit, I would stick with the Walnut stock, and the fin has a different sideplate than the chasse. Also the fin would generally have brass furniture while the chasse would be iron. Hey, welcome to the forum, Tonish, sure would be nice to know a little about you in your profile, and where yer from, being as we're pretty friendly folk here.
As a post script, both Henry, and TG, and a couple others have more knowledge in this area, I only reinacted, and researched French Militia in Detroit for 10 or so years, but I did stay in a Holiday Inn Express last night.
