For sale here is a Thompson No. 100 fly reel - made in San Jose, California in the late 1930s. The reel's diameter is 3 3/8" but the spool width is more narrow than the Model 500. Similar in style and performance to the classic Hardy Perfect. The reel is in excellent condition overall. Circular line guard. The original reel foot was filed on both ends so a replacement was made. Both reel feet are included in the sale. The No. 100 was built to handle 5/6 weight lines.
From Dan Homel's book, Antique Fly Reels, A History and Value Guide , "The drag incorporates a separate brake shoe for tension and pawl for click, both mounted upon lever arms fitted to opposite sides of a brake drum. The brake drum is provided with a smooth surface to accommodate the shoe and a toothed area or ratchet for the click pawl. Overall tension can be adjusted in various combinations between the pawl and brake shoe by means of two individual knobs which each drive a spring loaded stem against their respective lever arm. A recessed roller cage houses loosely fitted ball bearings to ease the entire rotation process."
