Perfect 3 1/8 inch diameter. Duplicated Mark II check. Smoky agate guide with 2 cracks. Smooth brass foot. Ivorine knob. Although the line guard is set up for LHW (left hand wind), the check is for RHW (right hand wind). The only way this reel can be properly fished is mounted on top of a rod instead of the down position. This referred to "Rings Up" position. This reel was examined by John Shaner, with Hardy Bros. USA, who assisted us with identifying and describing this interesting reel. This reel dates from the late 1920's. Very good condition.
