colt cobra serial number

[bikeman549]

I have a cobra nickel #60104M on the frame. Problem is the crane has number 60067. It is only 37 away and I wanted to know if it would be at all possible the factory made a mistake, or if someone changed it for some reason at a later date.. It looks NIB.

Welcome to the forum. Either is, of course, possible with the factory error being somewhat less likely IMO. Even a factory archive letter is not likely to disclose such an error by its very nature. Even though most on the forum have become quick to disclaim "With Colt you never know". it seems that if a replacement had been done knowingly sometime during the manufacturing process, Colt would have renumbered or used a previously unnumbered crane.

BTW the valid serial number is, of course, the one on the frame.

Looks like 1976 on the frame. I would think that if Colt replaced the crane and/or cylinder, they would stamp it with the corresponding #.
