The final model for this series is this example of the 0077 caboose, which is two-rail but semi-detailed. This model was produced from 1939-42. For even more on Lionel OO cabooses see this article in the Train99 website.
In any case, these classic OO gauge models in good condition will hold some value as long as people are collecting Lionel trains! To my mind the most iconic model of this line is the 1938 yellow (cream) colored boxcar. The bidding can really get going on these, as it also can on the separate sale versions of the 0044/5/6/7 versions of these cars (or the kit versions of the same) in their original display boxes. For example, as I write this just yesterday a set of all four of the separate sale versions of the built up cars sold on eBay, low of $292 for the hopper and high of $515.50 for the caboose.
