You could be right brent , but i have never seen a winchester single shot in the flesh. Ruger no.1's are reasonably common, certainly not rare but are a classic in their own lifetime again imho. The best way of course to get a design or drawing of an action is to sit down with an action and measure every last detail and constructing a model in solidworks or something like that. Sadly 100+ year old actions aren't exactly thick on the ground.
