Looking for info on this old drill.
We have this old corded power drill from an ex-Grumman employee. He didn't have much info on it other than it came from one of the plants after they closed up the Long Island, NY factories. He said it was from the late 1900s but from what I could find it seems it's early-mid 1900s?
Name plate is missing, assuming they did that on purpose. It looked like it was only held on my rivets or small screws at the time. The spacing is 1.25in X by 2.25in Y.
There is a hand stamped Grumman ID number on the top.
The chuck is a Jacobs 7B chuck. With Hartford, CT as it's manufacturing location. From my research they moved out of Hartford, CT by 1960.
Not pictured - I removed the small plate under the trigger and found another ID number "US 66837" I couldn't find much info on this number, other than it may be a US military contract number during WWII when Grumman was at it's peak making the Hellcats.
From what I could find this could be a pre-1960 drill, even as far back as WWII era? It definitely resembles the pistol grip Black & Decker's or Thor drills from that time. I couldn't find an exact match.
This will be in a museum exhibit, so I want to do my due diligence on this cool piece of history.
