WANTED: 1956 Washington licence plate

Or a 1954 - 57 that I can change the year tab will work out too. But yeah, need that plate.
Gettin a '56 GMC 2.5 ton truck & I wanna register it as a collector vehicle without gettin a shiny new plate.

For those folks that trade/collect plates, I have a New Zealand auto plate, and a New Zealand motorcycle plate, a 70's WA plate, and a couple more recent WA plates (around my mess somewhere, but I do know I have the NZ plates in the shed).

Let me know if you can help me out. :)
