I think 'Marston' (sp,,the evil ranchowner) in Quigley used a '60Army. Wasn't that also what they provide Quigley with for the 'shootout ?'
In any event, your right, one can never have too many.
As far as 'conversions'...In Pale Rider the evil 'lawmen' were totin' some conversions, but I couldn't get good 'nuff look to see if they were Armys or Navys, but I 'think' I saw a couple Army conversions....
Ain't seen Sephrim Falls but aren't the actors in that carrying cap and ball revolvers ?
Ride with the Devil has a few '60Armys.
Very intersting question Long John,,,im interested in hearing the forthcomming knowledge on this'un,,,,,
