The other machine is a model 35.  Inside the case, the mechanism has a type box like a model 28, but it's 110 baud 8-bit ASCII.  The space that looks like it might house a Model-33 call control unit indeed holds the CCU.  I used to use one of those back in 1969-70.  It's gigantic compared to a Model 33, but somewhat more flexible and designed for heavy service.  (Mostly, my TTY experience is with 33s.)
