Your Damascus looks like mine except for the cabinet. My cabinet is not as ornate as yours. Mine belonged to my great-great aunt May, she bought it new in 1925 for a whole $25.00 from the catalog. My grandmother said Aunt May bought it right after she came to live with them. Luckily for me she still had the manual so I could properly thread and oil the machine. Since my great grandmother was a seamstress the machines were always kept in the house. So I haven't polished it but have cleaned it and used it quite a bit before I got my Singer 15-91 from my mom. It was so much easier to use than my 1973 Singer.
