yes.
the window in the lower head lug is different. in the pressed lug ref. 32 from dubois, the upper edges of the triangle window are "rounded", as if a small rattail file was used to shape it. (it wasn't; these are machine-made windows. horrors, huh!!) in the i.c. lug from m.f.i., the window more exactly resembles a triangle. the areas of the aforementioned "cutout" are angular, not radiused.
