KEEN two speed breast drill

P1030424

Bought in a charity shop, dirty and rusty.

After cleaning and lubrication.

Made by M.C. Gooding & Co. Ltd., Croydon, England.

The company was liquidated in 1959.

By George, Pete, I think you've got it! The handles are the same shape, the large gear is identical, what I can see of the black casting looks the same, and the knurled "bearing" thingy seems to be the same as well. AS for the breast plate, mine was probably a "handyman" version of the more robust cast one. Thank you!

Is that Diamond stamp look like this?

 

 

Here are some more pictures:

 

 

 

 

That's the identical casting, but mine has a knurled nut holding the crank shaft in place, where this one has a pin (on top in the pic) which must keep the shaft in place. And no "KEEN" stamp anywhere. Maybe mine was assembled on a Monday!

John, have you checked out this site?

Yours looks like a 477 or 483. Is it a 3/8" or 1/2" chuck,2 jaw or 3 jaw?

Looks like Goodell Pratt and Miller Falls merged with Miller Falls In 1931, they were considered a top rate tool company.
