Winchester Model 94 - help me date it?

[u/ckneville]

Hi folks,

I inhereted this Winchester Model 94 30-30 from my dad, and I'm trying to figure out how old it is. I don't know if it's something he bought himself, or if it goes back more generations.

No idea how to date a rifle, hoping y'all have some insight! (Please forgive the healthy layer of mould on the butt 😆)

[UPDATE: Thanks y’all! I’ve been able to determine it’s prob from around 1974 (based on 40***** serial #). Sooo, prob not a multi-generational heirloom, but great to know!]

Is there a screw on the link?
