BoJangles, I did find the tutorials last night after posting. But this machine is so different that the dis-assembly tut doesn't help much. For example, the tension control is on top of the arm. It is a very simple machine. Luckily DH is very mechanical. Even though he thinks I am nuts, I can tell he's anxious to get it apart and clean it. As far as I know the only thing missing is the belt. There are two shuttles, but may be too rusty to use. One has a bobbin in it with blue thread.
It has a coffin top that is in pieces - just needs glueing. But it is missing a carved piece on the front corner. May have to move one from the back and put a plain piece in the back.
I did find a patent date on it of Nov. 1, 1881. I will keep doing research. The Smithsonian has a manual, but don't know if a print version is available.
