NOTES: About older and newer chromed metal spools.
On early run 115's (see photo of corroded example) where the non-handle side bearing is stamped 40-114, this NEWER style spool will not fit. The shafts were different and the older 3 pc spools were distinguishable by the bumps on either side of the spool's center piece just before the sides flared out.
On the newer type 1 pc spool (shown in the newer photo), the juncture from the center piece up into the flared sides is a smooth turn. It is compatible with the 115 9/0 reels that have either the 40-114H or 40-114HL bearings in the side plate.
CHECK THE BEARING ON YOUR REEL BEFORE ORDERING!!!
