Where is the actual Winchester 73 used in the movie of the same name?

There were actually 2 guns made up for the movie, both were original Winchester's but customized for the movie to replicate actual 1 of 1000 models. As far as I know both are in private collections though one was on the auction block a few yrs. ago. Right now, on Gunbroker.com, a Uberti mfg'd. model 73 that was used in the movie 'Young Guns II" is on that auction site. Regards....Marty
