I received a refresh on Steam Era Freight Cars Reference Manual, Vol. 3 on Refrigerator Cars. These are the perfect-bound commercially-printed books. In the coming weeks I will be updating Vols. 1 and 2 to this style as well. You should see an improvement in image rendering due to the change in printing on these two volumes. The cost should be the same as even though costs have increased, the change in printing should offset the increase.
