1970s-90s Small Dealer plates. Dealer demo (DD) and in-transit (DX) plates.
1974 In transit $25. all other 70s $20 each
1980s and newer $10 each.
Have a tub with a few other years you are welcome to look through. Some are New some were used. Dealers got several of these for their salesmen to each have plus extras in case they lost or damaged one.
Would consider trading for the couple years I am missing. I'll add my need list later once I go through all mine.
