@Tinplate Art posted:Interesting that some tenders were diecast aluminum, instead of the usual zinc alloys often subject to crazing due to impurities. AF was apparently ahead of their game in that regard.
Flyer prewar has very few items that were cast in aluminum. Other than this tender, the most common would be the Zephyr, which was cast in two halves and then joined together (the roofs of these sets are polished to hide the joint). Flyer also did the 9915 engine in aluminum and like the Zephyr it was cast in two halves and joined together, with a polished band down the top of the roof.
