It would be impossible to upgrade this reel! A new in the box 4/0 Fin Nor with all paperwork from I believe the late 1950's, based on the catalog that came with it, but I am not a Fin Nor expert. Serial number is 224. Paperwork includes catalog, reel maintenance brochure, and price lists for leather cases and rods. Asking $1400.

Cheers,
John
