Well, the guys are sort of right in that the CM HALL LAMP CO. of Detroit, MI made the headlights for Ferguson TO20's/TO30's but they have the later logo 'HALLAMP' stamped on back by the mounting bolt. The early 9N Ford-Ferguson used the CM HALL big truck-style headlights. Both Ford and then later Ferguson used the TAURUS taillight in their lighting kits. Ford used them from '39 -'49. Now, Hall made taillights too but I thin they didn't come out until after '52 -check the FENA site. I have a few original TAURUS taillights, an original HALLAMP taillight, and an original HALLAMP worklight for sale so email me if interested.
