Yup. They both came from the some lot I saw at the Vlaardingen cab trader when I had "just" started with the hobby. He had about 6 of them. They were stored up high on a rack but I didn't know about their value then and I wasn't looking for table games at all.
The seller told me they came from the Stena Line, a ferry between Holland and the UK. They had bought them BITD but they apparently failed to meet either British or Dutch electrical standards and thus were not allowed to be used on the ships. Following this they were stored for years and years and because of this they are near minty. I love these kind of stories

I wonder where the others ended up....
