mine all covered up right now, I think the D9 was the singer version a w9 was w&w's
so a D9 came in a singer cabinet. The both the same machine, just after singer took over they became a D9 so 1905 up.
you got a super good price. seems like they take a 127 X ? needle, but you can short set a 15x1, short set = slip it down until it picks up the thread.
