Between the main vise thread up on the General board and the Wilton Vise Dating thread on this board, at least a dozen vises made between 1941 and 1/1945 have been posted here on GJ. The first one that shows up on the Wilton Vise Dating thread can be found on page 6, post #103. But I recommend you follow the directions I gave you above, repeated here again below. It talks through the features of the four early (1941-1945) models. The PAT PENDS/PAT PENS with the looping line were the earliest. Yours, like the rendering in the article you posted, came later, just before they started stamping the mfg'ing date on the slide key.I have gone through at least 20 of the 54 pages and none like it have been found. I have also looked at hundreds of google images and many more on Ebay.
The only one like it is from the Fox/Jet article .

I am pretty good at research and this one has me stumped so far.
That is why i asked.
Go to the Stickie at the top of the vintage forum. Find the 'Wilton vise dating' thread in the Index. Click on it. Go to page 53, post #1045. Click on the link provided in that post. It's an excellent succinct summary of information scattered throughout the thread on how to ID the four early pre-date stamp Wilton models.
Some of us don't repaint even when there's an unfair amount of original 'hospital green' paint left after carefully removing the fugly coats (like the babysh*t brown on this 1-46) often found on top of these beauts.I see a fair amount of original paint on that vise.
I've seen your comparison shots before. It's the best match I have seen.
Did you remove the key and look in the slot? Early models were stamped there.there is no date on the slide. That is why i believe it is an early one.
