You have a really nice Model 15 there on your hands and I might add a pretty rare one at that.
The machine you have has a plated stitch regulator plate. Very few were made with that plate on it. According to the Singer records I have there were 5000 of them allotted on November 9 1932. This is a very low allotment and I am not sure but this may be the only allotment for the plated stitch regulator plates made.
Usually the allotments are for 50,000 or even 30,000 but rarely will you have the most wanted model that the company made below 10,000.
