I pulled center section found a 3 gear cluster sandwiched between 2 thick trapazoidal plates. My number is 8N347216[star]. The star is stamped next to last serial number. I can't find anything in the books or parts websites that refer to this component. It has to do with 1951 experimental draft controls ford was testing and an additional control lever. There is a brass patent pend. plate riveted to the plate that's bolted to back of tranny housing. Another N mystery.
