Does any other type use this small font near the top of the plate?
It's a very problematic issue. In Israel it works like that. If you are familiar with somebody in the vehicle technical institute, where they perform an annual roadworthiness test, and it is the same place where they print the license plates, you can come to the guy you know, and for a small fee, or just a bottle of some good alcohol create whatever you want. Everything is possible, though i really believe the type of this particular license plate was OLDTIMER, of either of two kinds - FLAG or NO FLAG. It's like a Schrödinger's License Plate
Anyway here is a similar condition on this RR.
And you can find an occurrence of a NON OLDTIMER plate, with the same small font without a flag here.
