1952 singer 15-91 sewing mace and zig zagger attachment
 

i just recently bought a 1952 singer 15-91 sewing machine in a cabinet with stool. its in amazing shape and works like a charm. it came with just about every attachment i will ever need besides the zigzagger.

i found online where the part number for the zig zagger for my 15-91 is 160985. please let me know if i am correct.

also, it seems like i can find a hundred zig zaggers out there, but only a couple with the part number 160985. can i use zig zaggers with other part numbers? and if so, what other part numbers do i need to look for?

thanks for any help you can give me!
