[Sewing] need an old Singer buttonhole attachment?

[Rachel McConnell]

I have one and don't have a machine to fit it.  I don't know what models 
of Singers (or other brands) it will fit, but from the looks of it, it 
would be one from the 50's or early 60's.  Might fit a 70's machine too; 
I don't think the form factor changed too much in those decades.  If you 
have a machine like this and want to try it, let me know!
