Interesting Dunlap 5244

[PeterPeter]

There’s a million of these Dunlap 3.5” vise out there, and I have done a lot of searching. Have yet to find another that looks like this. Notice how the Dunlap name is cast into a little cartouche, rather than a tag, or just letters across the body of the vise. Anyone have a clue whether it is newer, or older? Is there a collector’s site out there where I can find more info?

Thank you in advance,

Peter
