@BenLMaggi posted:To be clear, you mean this one: Greenberg's Guide to Lionel Trains O Gauge- Volume 1: 1915-1928?
It looks pricey ($100+) but quality isn't cheap. However, a search online revealed he did a lot of books so I don't want to buy the wrong one!
Thanks
Volume 1 was published several years ago. Volume 2, covering Lionel O gauge from 1929-1936 is available now. Both books are the definitive guides to their respective periods. $100 each, and worth every penny if prewar Lionel O is your interest. Volume 3 is slated for 2025.
