Searching for cylinder set screw for mortise lock 91A

Question

Hi, I have a vintage mortise lock or Marks with a stripped cylinder set screw. It's brass and approximately 2" in length x 3/8". I believe it could be a 91A. I'm in Louisville, KY and having a difficult time locating this. I searched Habitat as they sometimes have mortise locks and supplies. Thank you for any information you may provide.

Cordially, Marylou
