1930,
I poked around the shed and found these the other day. First two pictures are the "drop forged" marked ones (on side number 41, other side 48 or 49).
Last two pictures are the McKaig-Hatch pliers featured elsewhere on the site I linked to, for comparison purposes. Thought I would throw those in to show the differences to anyone interested.
If the first pair is what you need, let me know.
