I appreciate the 1930s and very early 1940s era models shown in the 1941 picture above; that era represented an incredible change in industrial design. Interestingly, I've been searching the internet for such models in 1:43 scale over the past year and have found very few, unless you consider Brooklin vehicles, which are generally out of my budget.
The vast majority of K-Line and WBB "Street" vehicles were of later era models, so I have a bit of a "time warp" in my city scenes...as shown below, but this is 3-rail and is fun nevertheless.
