You said to look at it close, not trying to offend.
That would have been a nice looking Navy if left alone. the way the recoil shield's have been ground away so much that after the 1st shot I think the remaining 5 cap's [primer's] would fall to the ground from the recoil. I think someone was just trying to make a better Colt and things went wrong.
Now if you can prove it was done by Colt, which I doubt, [to many things wrong] then it would be a rare Navy 51.
