Used on both farm tractors and tractor-trailer power units.
1960-1969TR-100 (?) - TR-9999
TRG-100 - TRJ-999
Due to the base variations here, the plates will be listed in order of issuance, not by sticker date.
Undated plates with tab slots started in 1961. The first number was probably TR-100.
Sometime in 1971, with the TRG series, the position of the dash changed to the middle of the plate, between the letters and numbers.
This series may have stopped at TRJ-999.
1970-1976TS-C100(?) - TS-F999
Plates started again at TS-A100 in 1970 (maybe TS-C100), and it looks like the entire TS- series was reflectorized.
Also, the dash went back to after the first two letters.

1992 BASE????-TB - ????
There are a variety of numbering configurations between samples and issued plates on the 1992 base.
I'm fairly certain that these plates are no longer issued - but I'm not sure if there are any still actively in use.
