Best I can tell, the numbers on the siade are 0 5 16, so based upon BIG GUN's formula, I believe i have a 156 pounder. But the story gets better! So I now have this Anvil and tools, and start reading up on Blacksmithing, the basic tools required, and am now itchin to get started. A cople months later I'm workin out of town, and just happen to stroll into a local antique store in the town I am working. I go deep down into the basement, and way off in the far corner I find this portable or revit forge buried in the corner. Everything works except that the pump handle is weathered, and it is missing the drive belt. He was asking $367, and I picked it up for $250. I bring it home, replace the handle and belt, oil it up and it is ready to go! Two weeks later, out of the blue my other neighbor shows up at my back gate with a Post/Leg Vise (3 1/2" Jaws). I had never told him I was looking for a post vise, he just shows up with one. He said he was cleaning out his garage, and thought I might want it. Other than missing the mounting bracket and spring, the screw is good, and the jaws line up. Although he said you can have it, I gave him $80. So i am either incredibly blessed with the "Luck of the Irish", or devine intervention is telling me to hurry up and get my xxxx started in the art of Blacksmithing! Again, I appreciate all the fine input, photos and information posted by y'all on this site.
