Hello, I went back to the local antique show, and a vendor had a Stanley No. 1220 Hand Drill, (eggbeater style) Made in USA . Solid gear, 3-jaw chuck. What was unusual was the weight of it, very heavy for its size, solid ball end handle. This had either an extremely high polish, or was chrome plated? Vendor told me it was a Medical drill, I had never seen or heard of one by Stanley. I could not find a 1220 in John Walter's book, either. I didn't buy it, and I failed to take a photo. Any one have thoughts on this tool? Thanks, Lou
