[USMA:24337] Re: iVDR "inch" drives?

[Joseph B. Reid]

Further to USMA 24335 in which Carleton MacDonald gave examples of approximate translation of sizes between inches and millimetres, French plumbing uses British plumbing standards (possibly the French got the bathing habit from the British who learned it from India). In France a 1/2" pipe is "un treize" (a thirteen) and a 3/4" pipe is "un dix-neuf" (a nineteen).
