Purchased a 5140 on eBay for a song on excellent shape! Rear spade handle is missing! Ereplacementparts,toolbarn parts, and sears parts direct say it's not available! This drill is also available as the Dewalt dw131.craftsman industrial spade and B&D 1321 and I'm sure other names! Parts list is same for all of the drills mentioned! Surely there is a place to get this handle!
