I'm a bit bias toward the NW trade gun but hear me out . I love its versatility and light weight but ...funny I found your post , I've tried to tell folks ,they are not only great game getters but also they stretch such a long period of history for reenacting . People tend to think of the NW trade gun as a western Mountain man firearm but it spanned such a long time period . The cast serpent side plate was introduced in 1749 . So ....isn't that crazy ?! So kinda think 1749 to say 1849 , just to make it easy to remember . Thats crazy ! F&I War , Rev.War , 1812 , western movement , fur trade period and a bit beyond ... Now , dont get me wrong , there were differences in the early ones but the gun adhered to a standard pattern so the differences were subtle and most folks , the vast majority, would not know the differences . The one difference that folks would notice is the trigger guard . Early trigger guard had much smaller bows in them than the post 1780 trigger guards . Approx. 1780 , via T.M.Hamilton ,. So .... If you get a N.W. Trade gun and have both styles of trigger guard made for it you can just switch the surface mounted trigger guard and use it in so many different time periods . Kinda neat ...Lads, I'm asking specifically for input on what sorts of reproductions can be used for the widest spread of impressions and time periods for reenacting purposes in the interest of thrift, not the general utility of the gun.
