evans rifle in crossfire trail

[Nyles]

I think the rarest gun I've seen actually fired in a film would be the Steyr 1912 in Michael Collins. Of course the Evans, being manually operated, requires less work - which is probably why you see more rare western guns actually fired than others. Another good one is the Starr 1858 in Unforgiven - I'm pretty sure it's original. I don't think repros were even being made at the time.
