According to my math the difference is even less than 4% which would make it even less perceptible. The decimal equivalent of 1/48th is 0.0204 and 1/50th is 0.0200. That difference is 2%.
Applying that to the various Detroit PCC O gauge models, the post-war Detroit PCC’s were 49 1/2 long. A true 1/48th scale model of that car would be 12.12” long. A true 1/50th scale model would be 11.88” long, almost ¼” shorter, or 2%.
