Sargent #422 Plane (1907-09)Sargent Planes Comparison Page - Shows some side-by-side features used for dating these early planes (below) The #422 plane in the foreground (418VBM in background) has cleaned up well thus far and appears to have 85-90% of its original japanning and the finish on the tote and know buffed well. The frog also has much of its japanning. (below) The brass height adjuster screw is cross-hatched, an indication of manufacture prior to 1909. The soul looks really good and appears to have nearly all of its original milling marks still showing. (below) The mouth of the frog mount is thin cast, but with square frog mounting hole bases, and the plane measures a thin 2.75" wide making this an early model from 1887-1909 (Type 2 according to David Heckel - SARGENT PLANES IDENTIFICATION AND VALUE GUIDE, 2004 2nd Ed.). The tote and knob are Rosewood, another indication of production from 1887-1909. The knob has a sizable chip out of it, so it is not perfect. The twisted Wright's Patent Lever has the requisite Feb.3 '91 stamp and is normally found with the horseshoe adjustor, but this example has the second patented adjustor on the end that specifically dates from 1907-09 (according to Charles Hegedus whose Shaw Patent Case Study is in Heckel's book on Sargent Planes). This appears to be a short period of production and may indicate greater rarity. In 1910 all adjusters had U-shaped adjuster levers through the end of production ~1960. The blade is stamped with appropriate Sargent emblem and can be dated to 1902-09.
