I recently came across my great grandfather's Wright and McGill 3 piece Granger Victory fly rod and Pflueger Sal-Trout 1554 reel (with his fly line still attached!). Overall, the rod and reel are in pretty good shape, however the reel has what appears to be some oxidation in places. I would like to restore it to some degree, but am hesitant to take away from the originality or do more harm than good. Any suggestions for materials and/or tactics for restoring the setup? Thanks!
