Can anyone help me with the age of this 305 ?

This just arrived today from eBay ( not exactly in the condition I thought ) and I'd like to know a date range for it, I believe it's a Camillus manufactured knife but to be honest I'm certainly no collector or expert or anything.

That looks like a Camillus knife from 1974-1985.

By the way, I discovered that the coping blade had a burnt tip where someone took it to a belt sander so I turned it into a small awl and In doing so removing the problem area.
