Hello, These 2 have been kicking around for a while. The one at top is about b7" long, I first thought it was a file handle, but the ferrule end is only about 1/2" deep, concave internally,and 3/8" in diameter. Possibly used to drive another tool??? The one at bottom looks like it may have been part of something else, chuck tightens by holding the larger wheel, or with a chuck key, barrel/shaft is hollow. Pin vise?? Part of a jeweler's lathe???? Thanks, Lou
