"Made In China"?

 

[Likely Guy]

Copy and paste from: http://www.gotheborg.com/index1.htm?http://gotheborg.com/qa/madeinchina.shtml

"As a general rule the plain "CHINA" mark came into use after 1891 when US federal law required all imports to be marked with their country of origin.

The addition of "MADE IN" was required from 1919."

So, that only tells you that it's no older than ninety+ years.
