1. It is a Singer 12 "Clone" I'll have to do some digging to find the maker. (first thought was a Henry Stewart, but...)
2. It is NOT is gross condition. it is actually in fairly nice condition.
3. Based on the bobbin winder I would guess 1890-1905 for a time frame.
4. The spacing of the two spool pins will be a key factor for the ID. most were much closer together on 12 clones
SchutzMark is like Trademark in the US
A Singer Model 12 manual will work for this in virtually every respects.
Does it have the shuttle?
I would STRONGLY suggest against stripping and repainting, but it is certainly yours to do with as you will.
EDIT: here is a machine with the same bade unfortunately listed here on NEEDLEBAR as "unknown"
