It is part number 8417-085. This is the modern black (or dark dark blue?) version of the classic 50-83 crew man who sat on the #50 gang car, the 3520 radar car, and the various TV cars. This exact one was used on Lionel's 18417 from 1993, the first Lionel re-release of the famous gang car. It was a New York Central version, so they painted the men black rather than blue.
This is a brand new NEW OLD STOCK replacement man. This is a part MADE BY LIONEL as a re-issue. We obtained it about 12 years ago in a dealer parts collection.
