this may interest Coaly more than others but I had a fellow in my office the other day and he assembled boxes and hung the doors for Fisher SE when the channel was welded to the front on the outside. He signed his stoves DP, DH, or DPH it depended on his mood the builder is David Hunter. He welded the flue and hung doors and he would do 32 stoves a day. I know I could not but that is what he said he used to do.
