So I've seen such beautiful restore jobs done here it makes me wonder how someone would go about the job.
For exampe I'm looking at that beautiful Colt SAA listed on the EE for $4100, or $4500 with the second .455 cylinder. How did Dingus go about making it .45 ACP? Would you order it in as .45 colt, and then have a gunsmith alter the cyliner to accept .45acp, then de-register it? Or would it just be something as simple as ordering in another cylinder (which seems to be the answer for this one as it has two cylinders)? If you did order a .45 colt SAA could you have it converted to .45acp or .45 schofield and and then get it de-registered?
How much can be done to an antique firearm in repairs and it still remain an antique? If a revolving cylinder is badly damaged could it be swapped out with a new modern one of the same caliber? Is this still an area that's considered that the frame is the firearm, and the barrel, grip, cyliner, stock, etc, can be swapped out for repairs or new parts?
