Oh, I also FINALLY found a 1956 Oklahoma truck tag. My wife and I go looking for antiques fairly regularly and we always take the time to go through old license plates. I had no luck finding hardly anything from '56. On a whim last week I did a search on craigslist and found a local guy selling plates. He had several '56 plates so I met up with him and picked up a truck tag. Before I bought it I called our Tax Commission and checked to see if the number was able to be registered and it is good to go. The guy I bought it from gave me the info of a guy who restores them, so I'm going to send it off and have it restored and looking brand new.
