Circa 1925 green baggage with the later trucks but no journals and no slits punched out for journals.

In 1925 IVES started adding journals to the trucks of their 9" passenger cars, although the smaller cars didn't get journals, Ives did start using the same trucks with the slots punched out for the journals when they ran out of the old trucks somewhere between 1925 and 1926. These cars are also found in the old red color, but green was new in 1926. 

The 61 may be somewhat harder to find than the other numbers during this period. No matter what you might see on someone's shelf. IVES never sold all four cars in the same set.

Here's the number 61 from the bottom, note the hollow rivet on the truck and that this car was lighted. The catalog listed these cars as 61-3 (the 3 was for third rail) even though that number never appeared on the car. All except the baggage car can be found with lights.

Ives went back to the "Parlor Car" name in 1926, as opposed to the "Drawing Room Car" name found on most of the 62/72 cars the previous couple of years.

Just like the rest of this series, green, steel litho on trucks punched for, but not having journals. Same period below, but in red.
