A 33 is the cheap common clunker that's designed for intermittent duty (4 hours per day max). It was often used in non-stop application, in which case it will frequently break. A 35 is a much heavier, much less common, machine that IS designed for 100% duty. I think a 37 is, roughly, a 35 with upper and lower case. Mechanically, a 33 has a print head that looks like a little cylinder, vaguely like the Selectric ball but a different shape. It turns to the right letter, then a hammer bashes it on the back to slam it against the paper. A 35 has a rectangular device that holds a collection of individual character hammers -- think of the tip of a typewriter arm, attached by the back to a guide. It moves to position the right character, then a hammer hits the back of the type guide to push it (but not the whole mechanism) against the paper. paul
