For your reading pleasure, I have scanned and posted Western Electric RS  
Specification Handbook Section 23.
This is like a 150 page sales catalog showing the characteristics of all  
the various Bell Model 28 gear (along with Teletype component numbers).  
Looks like a handy reference if you're trying to figure out just what you've  
got. I ran OCR on it so it should be searchable. 20MB pdf 
http://www.navy-radio.com/manuals/tty/28-we-rs.pdf


It has entries like the following
------------
28S SET OF  GEARS
This is a set of nylon gears (TP161811) for use with the 28C typing  
reperforator base to provide operation of the typing reperforator at 60 words  per 
minute.
Set number TP161811 consists of:
Motor Pinion part number  TP161790 (44T)
Countershaft Gear part number TP161784  (18T)
-------------
28A TYPING REPERFORATOR BASE (Teletype LRB3)
This  is a typing reperforator base designed to mount a 28A or 28B typing  
reperforator unit and a 28A Motor Unit for use in the 82B System.
It is a  receiving only base structure equipped with a three speed gear 
shift mechanism  designed to provide for operation at 60, 75, or 100 words per 
minute. The base  includes a tape supply reel, 2 terminal strips, a 16 point 
connector, a power  switch, a male three point twist lock power connector, 
a 4 ampere fuse, a low  tape contact which operates an indicating lamp 
visible through a plastic  button in the cover and an associated contact to 
operate the electrical  service unit signal bell on low tape. A matching female 
power connector is  also provided . The typing reperforator unit is driven 
from the gearshift  mechanism by a flexible timing belt.
Dimensions of this base are 13 l/2" X  13" X 9" .
Wiring is in accordance with BSP  P34.308.
