I looked at the #408 ( number tag attached to front of the forge ) Champion forge and checked out the blower like Trevor said and it was tight and turned both ways. The tuyere worked but was surprised that forge was only about an 1/8" thick steel and had rounded corners. I was told the forge came out of the old Whitney Estate in NY. Is this the type of construction for these old forges and how do they hold up with what I thought is thin metal?
Thanks Dan
