Now for the downside....I've seen this sort of thing before.
A buddy had his Dad's U.S. Marshal Service duty S&W parkerized at Joe's Blast&Park because it was scratched and worn, plus EVERYBODY knows Parkerizing makes it rustproof......AAAAHHHHHHHhhhh!!!!!! So much for history AND looks, much less class.
Let's see, some others. Turn Gramp's/Dad's WWII Colt into a FUGLY Bullseye gun by Bob's Gun Butchery. Bumper chrome the family Colt SAA. Scratch initials in all of Dad's Belgian Browning A5, with a pocketknife (Initials HN, if anyone sees one let me know!) and how about a parkerized Python!
I recently bought a S&W Registered Magnum from the original owner's Grandson. Box, certificate, and mailing tube included. I also got a picture and bio of the owner. Unfortunately someone let the gun sit in the box in South Florida. In the box it looks great! When you look at the other side it's rusted and pitted.
I say treat the gun with the same respect as the memories. Let real pros do the work and keep the class intact. John's rendition above is pretty classy! But what does a Redneck like me know?!
