This vintage Bill Ballan reel measures 2 7/8" in diameter excluding the pillars (3 1/4" pillar-to-pillar) and has an internal spool width of 7/8", it weighs a bit over 5 oz on my scale. I'd say it's perfect for a 5 weight line and would be suitable for a 4-6 weight. Reel is in near mint condition with no evidence that it's been fished; no scuffs on frame and no marks on reel foot. Does not include an original bag or case.
