Title: minature hex socket set
Post by: Charles Garrett on August 10, 2014, 10:42:22 AM

Has anybody seen or have a hex drive socket set where  the sockets are not stamped and are only 5 from 5/16 to 1/2".  Guessing that drive L handle may be smaller than 1/2"  Handle may be marked CURKO set #2.  Shown in
Knapp & Spencer catalog #27  ca 1924  page #531.  Sockets will be similar to Indestro but have lip at top for a retention clip on handle per Pat # 1328428 & Des # 59417.  I doubt that the hex lip was ever produced.  An earlier set wont have lip or retention clip.

Like D57775 ?

I think I have seen those sockets and assumed they were New Britains since
they kinda look like they were made on a screw machine....

Do not have any tho....:(

It is interesting that there are earlier patents for roller bearings by a David F. Graham assigned to New Departure (Probably the second largest maker of bearings in the world at the time), I wonder if it is the same fellow, and if he got in trouble for it? chuckle...
