After seeing pictures of box contents for older Colts, I was wondering if any of the pictured brushes were factory Colt. The diameter of the plastic bristles are; top brush, .440; middle brush, .640; bottom brush, .530. They are all twisted steel wire with a loop. Wire diameter; top, .050, middle, .080 and bottom, .070. Length as shown with a scale.
Thank you for your help, I was just curious;

I will bump this up since the holiday weekend is over and maybe someone could help me with an answer.
Thank you;

Thank you for your replies. Do you have any idea when Colt stopped supplying brushes like these? Also, given the larger diameter bristles on the middle brush, could it be for a .45 caliber gun?
