Carefully watch???? How can it be missed? It's so glaringly obvious it ruins 95% of the westerns ever made! By far most westerns simply border on stupidity when it comes to both pistols and rifles, there simply is no excuse for having people armed with 92 Winchesters in the 1860s and sometimes even earlier! Of course Hollywood was so far off on the true old west they might as well have called them science fiction movies and pretended they were on another planet! In Winchester 73 they got it really close so it's not like they simply didn't know and when considering the budget when making a film (old "B" westerns shot on a $2 budget excluded) I would think obtaining period correct firearms would have been a minor consideration. I think even the most ignorant producer would have known better than to use 1890s lever action rifles during the civil war era yet it was not uncommon at all to see them used in depictions of that time period, it's bad enough to see firearms that won't actually appear for a couple of decades but lever action '92s during the muzzleloading era just makes a movie unwatchable!
