Anybody need a Plvmb WF-76 (5/8") or WF-78 (3/4") 3/8-inch drive swivel socket? I think I might be able to scrounge up a few.![]()
The very definition of 'surplus'! Good lord!

Some guy in a truck down from the city. As you know, the problem with surplus is they're all the same size! Whatever surplus vein he tapped into up there, it favored Plomb empire tools. He had about dozen and a half drag link bits - all the same size, all Thorsen MFD U.S.A. He also had a lot of special "Proto TAC" (Tubing Appliance Company) drive tools attachments. See pics.

The patent on those PROTO TAC attachments is a TAC patent that dates to 1951.

Looks like a masonry drill.Hey guys... what is this thing?


Nice finds!...and a J.P. Danielson-made 710-SL 10" CLIK-STOP adjustable with a PROTO (R) PROFESSIONAL stamp and a "D 2 1" forged in date code. Has to be 1961. The Coslow Pendleton Tool Industries, Inc. era patent (2,905,037) was Sep 22, 1959.
Been away for a while since Tapatalk crashed and took several months to resolve but in that time I did pick up 2 S.R. drive tools. I have never seen drive tools but they appear to follow the Plomb WF series design. Very interesting thought on the S.R. orgins. I can't wait to see if we finally crack this one.

To your refinery point, Lugz, I have a socket and a Phillips driver, both obviously made by Proto, both marked Chevron. (found both at a swap right next to a Chev. refinery)
It's not exactly intuitive in context with the automotive tools they are best and primarily known for. None of the early catalogs (edit: in the public domain!) have anything but automotive or aviation mechanics' tools, and those (1925, 1928, and 1933) were explicitly published for automotive and aviation. I think the first catalog in TA library that includes masonry drills and concrete and soil pipe chisels, plumbing calkers and irons, and the like, is 1939, actually including "Plumbing" on the cover, along with an attempt to broaden the customer base for the mechanics tools (by also including "Oil Country", Railroads, Utilities, Mining, etc on the cover). Note that there are no special tools offered for those industries. 1941 continued that trend and the wartime catalogs shortened it to "Army, Navy and All Industries," but the masonry drills and chisels were gone. The 1948 catalog still had plumbing tools, but I'm not sure what happened after that.Never seen one before.
I have a Chevron marked screwdriver as well. It may have come from the Chevron refinery in nearby Richmond.

Mine is yellow plastic and I found it at the Concord swap if I remember.
I always figured that Chevron ordered custom tooling to discourage tools walking away. But that never stopped anyone...I can’t count how many estate sales I’ve gone to and found Chevron marked tools. I think it must have been a special perk for Chevron employees. Or possibly not.
I went to a garage sale a few blocks from home and the guy had Whitworth tools left over from ownership of a MG TD. I came home with these 3/8” drive Proto Whitworth sockets

It wouldn't surprise me, Slew. Most of the toolmakers that pre-date the era of automobile retail were making tools for other industries, especially blacksmithing, railroads, plumbing, etc, including Bonney, Billings & Spencer, J.P. Danielson, Champion DeArment (Channellock) etc.My impression was that Mr A Plomb started making such things perhaps before getting into wrenches,
Those look awesome.Here are a few I picked up
