Is the 'call control unit' -- the electronics chassis on the right hand 
side -- the same? I have a Data Dynamics machine (and I think it's a 
model 390) where the mechaical bits are normal Teletype ones, but the 
call control unit is very different. It's built on a couple of PCBs (!) 
and can handle both RS232 and current loop interfaces.

Believe it or not, the Teletype manuals for the Model 33 do have cleaning 
and lubrication charts for the cover...
