That is very cool. The Shempp collection in Williamsport is well worth a stop. Our paths actually crossed in the early '70s at a Rochester, NY train show. Mr Shempp, wearing a coat and tie, looked briefly at the HO brass I was selling then stopped at the next table with a number of Flyer standard gauge train sets including a Mayflower set. It was only later I learned who he was. A memory that has stuck with me.
