Favorite western actor who had been a real cowboy

Mine is Ben Johnson.  I think he was a stunt man too.

Peter Sherayko was Texas Jack Vermillion in Tombstone.  He also supplied most of the guns in the movie.

[C. F. 'Charley' Eckhardt]

'Texas Jack' was actually from Maryland.  He was called 'Texas Jack' because he preferred Texas-bred horses.

The firearms consultant for Tombstone was Lee Silva.  The 3 'Buntline Specials' were custom-made by Colt to Lee's specifications.  They had 4-screw 'black powder' frames & 10" bbls, which is what Lee's extensive research into the Buntline has convinced him was the actual bbl length of the original.
