One wrench is marked 0 6164 DB53 and the other is stamped H.N.



Here are a few wrenches with markings 1st on has R1 inside a circle stamped on the end and is 1 x 1 1/8 (top wrench). The 2nd wrench has the number 379 on the center of the front and 9/16 & 1/2 on the ends (the nut sizes are much larger than marked). The 3rd wrench is marked with the number 6491. The 4th wrench has just the letter S on it. The 5th wrench is marked MFD USA and is 9/16 x 1/2.

The second wrench down in the last photo may be IHC. Rathbone lists a 379 and the picture looks right except there are markings both to the right and left of the 379. I can't see the detail to tell what they are. The mark to the right is round so probably IHC.

 Second wrench should be IHC. Irps lists 4 variations of that wrench and they don't all fit same size nuts.

I believe that is a dodge wrench

Funny, it doesn't look like an S wrench...(ducking).
Probably for 'Special' , eg, a non standard size pair for someone

>MFD USA

The panel design is the thing on that one, but I forget whose it is...(indestro????)

0 6164 DB53

I belive that the 0 in front is really a Q,  and the DB is for Dodge Brothers.
