Never used. Made by by Aldon in Detroit circa 1970. Found with several other Aldon made planes and shaves (in their original boxes) I am listing this week. I have only seen their mini shaves and one router before, never these double shaves or the tailed mini planes also listed. Used by luthier's and patternmakers. Made in America quality!
