The wedge screw is of particular interest to me.
I just bought an ASM Colt Addressed Third Model Dragoon from Cowans/Little Johns and it has an identical screw.
When I first got it, I knocked the wedge with a rubber mallet and it went flying.
After crawling around looking under the workbench for the very aerodynamic wedge, I looked at the retaining screw and saw that one side of the head was flattened.
My first thought was that I didn't know my own strength and had hit the wedge hard enough to shear off the side of the screw head.
On closer examination, I saw that the flat side of the screw was BLUED!
Obviously it was made that way and it was aligned with the top of the wedge when I hit it allowing the wedge to exit the barrel completely.
I have never (until this auction) seen another wedge retaining screw made so that the wedge could be completely removed just by aligning the flat side with top of the wedge.
All of my other reproductions have screws with fully round heads which require one to completely remove (drop and loose) the screw to remove the wedge.
Has anyone seen similar screws on reproduction or original Colts?
