Series 70 Engraved Colt
I just purchased an engraved Colt on GB. It was advertised as factory engraved, no box or papers but with presentation case. Pistol is unfired. Engraving appears to be "C". Should I get a letter. Looks like a letter will cost about 250. I kind of choked at over 200 dollars for a letter. Will it add that much to the value?.
