That is a push drill. Old school.I'm going to guess that is from the 1960's maybe 50's. I have had a few of those. If you have a cordless drill I would mount it on the wall and look at it. I've put a few on Ebay and they don't sell for very much. If you go to estate or garage sales you'll find bits for these in the bottom of drawers or coffee cans as nobody knows what they are for.
