A quick followup now that I have received the revolver. It is in very nice shape. The serial No. is in white grease pencil on the bottom of the box. The sight post looks perfect to me. There is no lint nor ding. There is an indentation, but it is not deep enough to have held any type of bead for any length of time, so in my opinion there was not ever any bead there. I inquired of one other 1955 k-22 owner and he indicated there was no bead on his collectible-quality k-22 either.

I will try to get pics up, but be patient with me. I am not a photographer.
