B58-630 COMBINATION CORNER BRACE. Haeberli & Schmidt Patent. One of the rarest and most gizmoish braces, patented in 1907 by two guys from Buffalo and sold (briefly) by Goodell-Pratt. Ranked A for rarity by Pearson, and for once Ron's ranking is still accurate. The bitstock can be removed from the angle brace frame and used as a traditional brace. Marked only "Patent Applied For." In nice clean overall condition with 95% japanning; the spring-type alligator jaws are chipped but you could easily replace them with jaws from a $5 brace. Good+ 300-600
