Age of S&W 66?

[Walter W.]

I don't know where to find a manufacturing date for S&W guns online.

I have a S&W model 66 with a seven digit serial starting with 4K503. It's not with a -# after 66. It's just a plain Model 66.

Can someone help me out with a site or book to look this up in? Or even better, does someone know how old this is?

Thanx!
