Vintage Leonard Precision Products Co USA Hex Allen Key Driver Square Shank Tool

Pulled this out of a bunch of old tools. the handle seems to be cast aluminum although I could not find another one to compare it with. the hex key itself has some surface rust and the handle has definitely been used. stamped manufacturing label still looks great. pretty cool little tool and collectible. let me know if you have any questions thank you!
