Well you sent me off down a little rabbit hole. The set I got was in 1984. Looks like they kept producing sets with that shield type well into the late 90s.
There’s a video here that covers everything from 1978.
edit: didn’t see your recommendation until after but appreciate it :)
Yep, recognize them from sets I got in the early 90s!
Brickset.com might help you jog your memory and identify some sets, after that finding instructions might be another challenge though…
