Yes it is strange, but as we all know Jensen he used what ever he had. So if he found paint that was still good I'm sure he would have used it. We all have to keep in mind that he was building a toy. He never knew that people would be collecting and restoring this stuff. I'm sure he figured this stuff would end up in the trash pile. I'm sure a bunch of it did. I have a model 20 big power plant that was in a dumpster a friend of mine got out and brought and give to me.
