SteveH,
Thanks a big bunch. Just what I needed. I had looked at ISMACS and totally missed that chart.
The Smithsonian manual is probably the best match to this machine.
Cathy,
I think this one is Pre Model A type 1. More like the New Home New Style shown towards the top of the page. The description fits my machine as well.
It has the round shuttle and flat needle bar as well as the square corners. The Model A's show rounded corners.
At any rate I finally did it, a pre 1900 machine, 128 years old ........ WHOOO HOOOO!!!!!!!!!!!!!!!!!!
