I did that on the Model T Ford I had several years ago. I found a pair of 1923 plates. I did that with my Willys Jeep. It sports a pair of 1947 truck plates. During this time I found out that for trucks you only have to have one plate. I wanted to do that for the M416 military trailer and actually have a 1965 trailer plate for it. However, the registration rules cited above for vehicles over 30 years old does not apply to the trailer because it is not motor driven. I have a plan though.
But, when it was time to put a license plate on Lou it took three tries. When I bought him I thought he was manufactured in 1976; that is what the ad said on the Internet. I ordered a plate from the guy I have been getting these plates from. I discovered at the Department of Licensing office that the title said manufactured in 1967. I had been puzzled because I couldn't find specifications for Lou later than 1972. Now I knew why. So the plate and tab I had bought wouldn't work; wrong tab, wrong plate style. I contacted my plate guy but the plate I wanted 1) was more expensive (older) and he would only credit me 75% of the cost of the '76 plate. Being thrifty, I had an idea.
About a year ago my son and his wife won a "collector plate" at a benefit auction with the idea of giving it to me. The problem was they kept forgetting to give it to me, until the very week that I was going through the process of licensing Lou. It came in the mail. My idea was to take the gifted "collector plate" in and use it to license Lou. That didn't work. You have to have "collector plates" issued by the State of Washington, you can't just bring one in. So I ended up losing a little money and buying the more expensive '67 plate. Lou is now registered with the '67 plate shown below.
