Printing Selectric

This is an IBM  Printing Selectric I plan to restore. It is probably an OEM version of the IBM 2741 it is a ruggedized teleprinter version of a regular IBM selectric typewriter. I do not have the control electronics. I am searching for a service manual. The only thing I’ve found is an operators manual

 A mouse apparently took up residence.  

This will take a while to trace so I’d prefer to find the manual

Label says MT/ST Model 775

This is the I/O connector I need to trace
