And this has the top leaf tension and the narrower throat plate (this one I'm sure in teh National Seamstress model, I own one like it).

I still sew on my mother's New England Queen that was made by National in Belvedere, Illinois. Mother's is in an oak cabinet with the same leave design on the front middle drawers as in this eBay picture that MacyBaby posted. It is the exact same cabinet, only the black iron has N.E.Queen on the sides also in black iron.
