The base and the screw box are definitely cast and the legs are drop forged. When taking the paint off with wire brush it seemed at first like there was grey paint that wasn’t coming off. Turns out the imperfections in the cast parts were filled with lead and filed smooth.

Thanks for your response. I guess I should have been more specific when I said “specifications.” I have seen in pasts posts on this forum of old technical diagrams of vises and other tools. I have searched the US patent server, but there is over 45,000 patents listed when searching for “vises.” This vise is in Central America and most of the old tools (anvils, vises, sawmills etc.) seem to originate from Europe. Might not show up in US patents. I agree with your observation about the hinge pin. Although the pin is 2 inches in diameter, the casting would be a weak point if hammering with great force. I removed about 6 coats of paint from the vise, looking for any stamps or maker’s marks and didn’t find any. Each separate piece is stamped with the number 19, but I would imagine that it was to identify the individual forged pieces to their unique unit. Regarding your “last note.” While researching this vise, I was referred to this forum as a great resource because many of the members have experience in metalworking and blacksmithing and are experts in the field. I appreciate the post from LeeJustice, but I had already reached out to the Pflugmuseum in Switzerland and the poster on Pinterest a few weeks ago, but they could not help. And of course, when I was removing the paint, I did look on the underside for markings and couldn’t see any. I will continue hunting for information. It is a very interesting vise and would like to learn more about its history. I will post any findings here if anyone is interested. Thank you Frosty The Lucky for your response.

I was wondering if someone here could help me with info (age, manufacturer, specifications) of this large vise. It has 11 inch jaws and weighs at least 400lbs. The scale I used only went up to 400lbs. Appears to be much heavier.
