Hello

As Mike says, this is from Heifetz - the copy is from the second edition but it is now in a  third - on which the corresponding page has a new ERD (18/9/45), 542 covers seen and from 61 countries.  Current ISBN is 0939429225 and it's listed for sale on the AAPS website.  (And, yes, it is an extremely useful resource if you're interested in 1940s air mail).
