Kr-23 snap on machinist box identification help.

[Ksem89]

Hey guys, I picked up this box full of tools on auction.

The best I can figure is it's a KR-23. However I cannot find the model number/on it.

Can anyone do positively identify the model, and maybe date?

Thanks!

If it is about 20" wide its a K22, if it is 24" wide its a K23. would date 40s. the stamped model numbers show up in the mid 50s

It is 24" inches wide. And that makes sense as to why I cannot find a stamp.

Thank you!!
