Speaking of consecutive serial numbers, how about a pair of Colt OMM numbered like that? One in .22 the other a .38 Spl. Unfortunately they, along with a pre-War Colt OP, mint in the box, went into the kitty a few years ago when I was putting together a down payment on a house. The OMM .22 was beyond a doubt the most accurate .22 revolver I ever fired. As a friend said to me "It shoots like a young rifle!"
