The Calso station started life as an Ameri-Town flag stop station, with a scratch built canopy and Berkshire accessories. Calso was a Chevron brand in the northeast during the 40s and 50s.
On another thread there is a discussion about diecast automobiles and scale. My thoughts are go ahead and buy quality vehicles, as they look much better, especially if your layout is hi-rail. Not all quality vehicles are expensive, but the high-end manufactures offer a large number of common every day makes, not only 57 Chevys and 65 Mustangs.
Many appreciate in value as well. The USA Models1955 Imperial has doubled in value, but the Franklin Mint 1950 Nash Rambler can be found on e-bay for about half its original cost.
I am as much of a car nut as a railfan.. I have been collecting 43rd models for years and have a large collection. What better place to display some of them than on an O gauge layout.
As to scale, 1/43 is about 10% to large, but it looks OK. Just be sure to keep some space between 1/43 and 1/48 models.
