Looking to ID my Model 36 manufacture date?

[Five0retired]

I have a S&W model #36 , serial number on butt of gun is stamped #200J7. I am finally getting around to cataloging my weapons. This one I acquired from fellow P.O. back in 1996 can't find the paperwork so I don't know the year of manufacture . Would appreciate any help I could get .
