There are no other markings. It's the only snap on I could find. Perhaps a replacement since there were SAE bahco MIS sockets but no 5/8?1940's, and, based on the finish, which is either natural steel or worn and faded cadmium, likely WWII. Is there no other marking besides the branding, size, and the model number? They were usually date coded, but not always. Either a funny looking number or an "E", "G", or later perhaps.
Was it an orphan? Or is there a set or partial set?
Nono dont feel bad about, I'll take you for your word, I'm asking because I didnt know and want to learnIt's definitely not from the 20's. The sockets were very different. Cold broached. Big band of knurling around the middle. The logo did not change (slanty, and true hyphen) on 1/2 dr stuff until 1948 or so, a little earlier on Ferret. I don't want to come off condescending, but I am not guessing in the dark here. I have 20s, 30s, and 40s Snap-on sets, and lots of wartime. That is a 40s socket, and likely wartime. Others will confirm when they wake up and log in.
