William Olson Gear and Pawl Fly Reel 4" Salmon and Steelhead Rods The reel diameter is 3A very nice William Olson Gear and Pawl fly reel, 4" diameter and set up for RHW. Black anodized throughout with a clear anodized foot and S shaped crank handle. Two handsome medallions are inset into the front plate with the first noting the original owner's name, model (4" G&P), and serial number (No. 275) while the second bears William's maker stamp. The reel weighs 12. 6 ounces on my scale. It is in mint, unused condition. Ebonite style handle.
