I bought a plastic spool from eBay that is factory marked 29-155. I needed a spool for a 180 and decided to take a chance on this one. The seller (whom I've done business with and trust) called it a 155 JR spool. One photo clearly showed the part# 29-155 and another photo showed the spool next to a ruler. It was clearly much narrower than a -155 spool. Anyway, it fits nicely in my 180, so it is truly a 29-100 or 29P-100, or something like that.
Has anyone else seen a mis-marked Penn spool?
at least your spools are marked. i have a bunch that are not and i have no idea what they are.
Alan, you could always send them to me and I'll try them in my Penn reels ;). Just the ones that you suspect are Penn, though. I'll pay for mailing them back to you, minus the ones I might purchase.
there are hundreds...... :-\
