The gear chart shows same gears for 74.2 and 110.  (The 159284 & 159285 are also shown in the parts section for the 35 keyboard.)

I’m not sure the start and stop bit lengths for 110 baud, but let’s say they also add 2.42 bits for a total of 10.42 bits. I calculate the model 28 at 75 baud is 10.1 characters per second and the model 35 is 10.6.
