I got a box of metal spools last year and these were not marked. Does anybody recognized them?
Spool 1
Spool 2
Spool 3
Spool 4. The sides of this one are straight with no taper.
I think #4 is from a 980 or 990.
Number 1 and number 3 look like Newell spools. I'm not sure if they're for Penn's or if they are for the Newell reels.
Edit after checking a pic of a Newell spool for a Monofil 27 they may not be Newell. The star pattern on the side of your spools is different than the spool I have, also the dots are different as well.
