Neither of my forges has any identifying marks on them, only the blowers. However, I happened across this scan of a page from the 1920 Sears Roebuck catalog, which I believe may identify both of my forges:
The “Whirlwind” forge on the bottom left is the closest I’ve seen to my small forge. The three legs, the bracing, the shape of the spokes on the wheel, even the location of the hood … I can’t see anything that doesn’t line up.
It’s a similar situation with my large forge, and the one pictured in the center (the “Acme combination forge and blower”). The shape and dimensions of the forge, the shape of the firepot, the arm that the blower mounts on, etc. It all looks identical.
Unless someone can give me a positive ID for something other than these, I’m pretty sure this is what I have. In the unlikely event that someone happens to read this post and has other information, please don’t hesitate to post a reply.
Now, if I can only find a way to positively identify my anvil, I’ll be a very happy camper!
