Plomb 47XX midget socket markings questions

[Private Lugnutz]

I need some help on this recent acquisition, a circa 1941-42 partial Plomb 4700 midget set…

So, nothing unusual about the box with these markings and the OD (“GREEN”) crinkle finish (instead of the “brilliant Chinese Red” they had originally planned).

And there’s nothing unusual about the 4749 ratchet.

But two of the 47XX series sockets have some strange model numbers.

These two, in particular…

Here are the sockets with model numbers that match the 19R catalog:

4707, 7/32, 6-point
4708, 1/4, 6-point
4708 S, 1/4, 8-point
4709, 9/32, 6-point
4712, 3/8, 6-point

Here are the two odd sockets:

4710 H (or possibly a worn R), 5/16, 6-point
4710 K-S, 5/16, 8-point

Anybody know what the H or R and the K-S signifies?

S is typically used across industry for an 8-point socket. And Plomb adhered (as in the 4708 S above). But I’ve never seen a K-S or an H or R.

Hey Lugnutz - I've got four of those 4710s. One is marked K-S, the others S. I'm afraid we'll never learn the meaning of the K. The collectors have puzzled over the letters on many tools for years and no one has a good answer.

Lug: I don't have anything to add, but that's a great find!

First off, you **** majorly for this find! I am looking for one of these ratchets and some other 1/4 drive sockets to fill my plvmb box that is the same color and size as yours! The small stuff is hard to find. I have no clue as to the letters on the sockets? Hopefully someone will chime in??

I had a set of swivel sockets with the letter markings after the model number. They were all wf series sockets with the letter after model number. I noticed the stamping were done on the nut side of the socket and upside done done with a "p" stamping. When I asked about it on here a couple years ago. I remember a member talking about mint marking for either a different line or factory it was made in. I am not sure if this is the same sensei but I am going to look over my plomb items to check for it.
