No, it's not a big deal, I was just a bit surprised that you seem to know more about it than the lady at the RTA, who has worked there for at least 20 years that I can remember and has to process all the local historic plates in my region (probably 200+/- cars and bikes).

I guess she's just doing her job and not really interested.

And you are right about the Police not knowing how to administer it. I'm friends with the local Police Area Supervisor and he saw my blown Torana in my shed and wondered why it wasn't on historic rego. I didn't spill the beans and tell him it wasn't eligible, I figure if he doesn't know, then the other cops probably don't either.
