Very nice! It's been a while since I looked at at 33. I see it is using a
type drum as opposed to the type box of the 28 or the type bars of the 15.
I think the type drum was used in a Morcrum printer used by AP in 1915.
There sure are a lot of different ways to get text onto paper! These
various "impact" printers including daisy wheel ending with dot matrix
impact, thermal dot matrix as was common in fax machines, xerographic, and
ink jet.
