Looks very similar to my Buffalo #3 Boilermaker's forge (21" x 27"). I just posted about it here: http://www.iforgeiron.com/topic/43858-how-thick-of-a-refractory-cement-lining-in-a-coal-forge/ Here is a 1906 Buffalo Catalog that maybe helpful: http://www.vintagemachinery.org/pubs/129/5083.pdf Here more pictures of mine to help you figure out what maybe missing:

My kids (8,10) asked me if we could o some blacksmithing* so I said yes, because I'm a sucker for anything that does not involve screen time. The next day I found a coal forge on the local CList and bought it. Now they are helping looking for the rest of the tools we need (anvil, leg vise.) This activity will round an existing home shop set up to do light forming, welding, and machining. My day job is in a shipyard, fabricating aluminum boats and inspecting welds. I look forward to participating in the conversation here. " It's easier to jump in, than wade in." *

I recently picked up complete Buffalo #3 boilermaker forge and have found some info stating that it should be lined with refractory clay or refractory cement. Where can one get these refractory materials, locally in the PNW? How thick of a layer is needed? Should the cement be formed around the tuyere to create a fire pot? Here's some pictures:
