We're getting some cool stuff now.
The 601/602 cars with Those are the second or 3rd version of the car. First versions had long trucks.
The baggage comes with block or serif New York Central over the doors. I have Serif lettering with long trucks and no stamp on bottom. Doesn't say Lionel anywhere on car.
Here's the interesting version with block NYC lettering and the Lionel Lines on bottom.
I inventory my train going alphabetically with oldest having letter A. The two cars above are A and C so there is certainly a car between them. These letters should match the latest Greenberg book.
Here's a neat stamp. I think 1924 and later.
I think that's the stamp that would go on the end of the box. The tender with this stamp is not rare, and the tender with slotted trucks can be found with or without the "6 Tender" stamp.
Here's picture of my monitor.
The little blue dude came from the 1991 TCA convention Banquet. I think you made them Jim. I should have a handful of them, but either the dog is eating them or they are hiding.
