old style bobbin winder, stitch regulater on pillar, round needle plate, top tension -
first off, I'm only good at US machines (and then I'm still guessing). It has the tension most similar to New HOme (but it's missing the lever) but I've not found research showing that New Home made a fiddle base machine.
Otherwise I'd think Eldredge/National, except for the top tension.
And I do know Standard used the Favorite name, but it has none of the tell tale Standard marks.
It is yours? if so, the form of the presser bar where the foot attaches is also an identifier, as is distance between the presser bar and needle, and if the needle is centered or offset from the presser bar.
