Go to the following site it gives some information about the portable forges I mentioned

http://www.cwartillery.org/artequip.html

Also look at the following site. It has a photo of a portable forge (this is courtesy of Paulson Brothers which is a modern manufacturer of reproduction artillery so I assume this is a repro. (But Paulson has a reputation of scrupulous authenticity) Click on the photo for a closer look
