You need to come and visit the museum Charles.  Yes, I did forget the 
34, but it was kind of an afterthought to make a 28 look like a 35. 
I am not sure it really was a "34" and not a 28 with a special 
designation for the cabinet.  I have never seen any documentation 
showing a model 34.

The numbers above 40 are three and four-digit  models, e.g. 4210, 
4220, 4320, 4330, 4410, 4420, 478, 479, 4550, 5310, 5320.  The last 
five models were the last built ones by AT&T Teletype in Singapore 
along with the AT&T UNIX PC.  Many of the 5310s are still in use 
monitoring telephone company battery plants.  They are a dot matrix 
printer-terminal (has a keyboard) with lots of options.  The 5320 is 
a wide platen version of the 5310.
