I see a shield, a flag, and an axe. Maybe some castle/medieval sets in there? Might be worth comparing to parts lists of castle sets from that era. Are these from before or after the 2004 light-grey colour debacle?
The flag, sword, axe and shield were all in a castle set I got for Christmas in the mid 80s! I presume they kept producing sets with them well after that though.
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 :)
