Rex never made an Andrew¡¯s truck with flexible leaf springs. ?The early 2-4-4T Suburban kit (my first loco build ar age 14, in 1953) had a Cult leaf-sprung Andrews trailing truck. ?And the cast wheels were robbed on the back side.
(These somewhat large Culp Andrews trucks are nearly dead ringers for the Benner¡¯s Crown trucks found beneath PRR Class H21 quad hopper cars.)
A few years later I reworked my Suburban into a true NYC Class D2-a. ?Main changes: shortening the coal bunker and altering cab appearance. ?No photos, but Dave Jasper currently owns the loco.
