I think Talespin is set in 1937 - before the WWII, but after the start of the Great Depression. The episode called "On A Wing And A Bear" depicts the energetic crisis made by Khan Industries, and the unemployment of the pilots after winning the race with Baloo by a robot can be associated with the Great Depression. But I wouldn't say Talespin must be historically correct, because this cartoon is for me the example of "baby dieselpunk".
However, ya can check out the articles about the most possible Talespin timeline and the explanation in the Talespin Sourcepage:
