The 5-digit serial number range posted may not actually be a serial number. For a Model 49, look for a number which starts with "1J", "J", or a three-letter prefix.

EDIT: Post #2 and I were posting at ~the same time. Post #2 has more info can aid in id'ing this J-frame revolver.

Thank you gentlemen, I found the sn after I took the grip off. J690xxx
I guess that means it was made during 1979-80.
