I've an Elite RP1 with a single tooth missing from the carriage rack (part 52, figure 1, plate VI, page 18 here: RemingtonPortableService1931.pdf (xavier.edu)).

Of course, the missing tooth is right in the middle: column 40 (guessing someone in its past didn't understand the the carriage lock and forced it). 

So, I'm looking to replace the rack with one with a full set of teeth if anyone's got one lying around. It is an elite, so would need the rack from another elite.

Thanks!
