Howdy! My oldest son is doing a school project on Winchester lever gun evolution. It's not a super deep dive, but it's deeper than my references. Something that will cover from the 1866 through the 1895 with the nuances of changes both between models and within models as far as changes within the models as they occurred.
I am looking for a reference recommendation that would help him in this endeavour.
Thank you all for your help!
(Mods please move this if I have posted it in the incorrect place - thank you)
