Help me out here, please! I can't find out anything about this socket that I found on the floor of a St. Vincent DePaul thrift shop floor. It's definitely a 3/8" 12 pt. socket with 3/8" drive square, as my 3/8" ratchet fits snugly on the male part of the ratchet. It's a semi deep wall being about 2" long. The part number though is drawing nothing but blanks on Google searches. It's either a n SF-120 or a 5F-120. Any ideas out there? I just have the one socket. In the future, I'll try to have more common stuff to ask about.....

Sure, They were made from 1939 to 1946 and were used for body panels (running boards, fenders and doors)

You can you the new - handy dandy - search function (up today for the first time) to pull the catalog listings for this socket

Great find - they are not common

Frank: If any of your forum folks want to obtain this socket, it's on ebay currently at .99 wit h3 days left. If there is a better place to post this info, I'll abide by those rules too.
Thanks for the help. Any more info on the Torqometer???

I have been thinking about this. As I was going through indexing Torque Wrenches. I ended up with a comprehensive list of Torque Wrenches from 1923 to 1965. I would like to complete this list up to 1979 before ripping it apart, but I do now know this

There are about 490 different Torque Wrenches (I may have listed a couple twice – duplicates) during this period. Using the first few letters as a way to sort them out (I am guessing these are types) there are about 10 types.

These are TQ with 263 different configurations, the TQA with 3 variants, TQAC with 1, TQC with 120, TQCD with 19, TQD with 34, TQE with 5, TQEC with 2, TQM with 14 and the TQS with 6

Within these types there seem to be options. I see a couple I understand and a bunch I don’t. These are:

SP means Slip Point there are 149 with this option, FU means Follow Up – 115, the next most common is to have no “options” – a plain Jane version – there are 94 of these, next is L meaning Light – 42, then the ones I don’t understand, T – 32 of them, TL – 19, A -11, AL – 9, B – 5, AF – 4, AFL (something Flash Light?) -2 and BL – 1 of these, and F – 1, STL – 1 and Finally Z with 1

Then there is a number in the middle – I am guessing the number relates to the stress range.

I have not taken one apart and I have not tried to figure out what the letters really mean – Any ideas, hints or suggestions??
