I showed the bottoms of these cars earlier and Mike said maybe trucks were wrong? The greenberg starts with 602C, but does show the earlyist car on page 55 in a 706 set.
Here's what I have:
Two cars with the long or half moon trucks and wide tread wheels. The 602 baggage has slots in the bottom and no lettering. All my baggages have door handles.
The 601 pullman hs no slots or lettering on the bottom. NYC over windows is serif lettering 3.75 inches long.
Here's the two cars:
I have three 601 pullmans with window film between the insert and the car body. I don't have a baggage to match these. They have the type 2 truck with two cutouts, and WIDE tread wheels. Frames have slots and The Lionel Lines/ New York/ Made in USA on bottom. NYC over windows is serif lettering 3.75 inches long.
Here's one of them:
Then I have another dark green set with the later trucks. This is the one with the block lettering over the doors on the 602. The baggage does not have slots, but does have the The Lionel Lines stamp. This car also has one truck with dimples. The NYC over windows on 601 pullman is 3.125" long, bottom has slots, but no stamp.
Here they are:
That's it for the dark green ones.
