I suppose this will be my first post joining the board.  Earlier this year an acquantaince gave me this Royal Portable, which at the time was in perfect working condition save the carriage return belt.  I replaced it temporarily with fishing line, but in the process it seems an important part broke.  I don't know the exact term, but I've called this the carriage stop, and the tooth broke off.  I don't know if this is repairable, but I think it's above my ability.

At this point if somebody would be interested in adding it to their own collection and hopefully repair it rather than part it out, I would like to move it along.
