Help With Stamps And Postmarks On This Cover

I just got this interesting cover, not super valuable, but sort of odd because it has 3 "St Johns" cancels: St Johns Newfoundland, St John New Brunswick and St Johns British Virgin Island.

I'd appreciate any comments or information for my records, like

Its #132 stamp from Newfoundland, but what is the Scott # for the Canadian postal envelope?

What is the US stamp number?

It was canceled in Newfoundland on May 6, 1927 and NB on May 12 and May 14 in the BVI--but in 1927...so how the heck is there also a Washington DC cancel on May 1, 1928 (and on the back at NY on May 2)?

What's going on with the purple cachet--a FFC between DC and NY?

What is the Wash DC to Richmond VA cachet ?

And did this travel by rail too--why the Rail & SS (?) cachet?

The back has a Varick St Station NY cancel on May 2 and two Merry Christmas labels, and also inverted cancels from Richmond VA and New York NY cancel on May 2...sort of feels like the cover had two lives but to whom? To Max Berendes in St Johns then he send it to himself again?

Enjoy and I look forward to your comments

Just trying to piece together a history and the facts (or guesses)

I can't begin to explain it all, but it looks to me like the cover was first used from St. John's, Newfoundland to St. John, New Brunswick, then onto the addressee in St. John, Antigua, B.W.I. That occurred beginning (what I suspect) is May 6, 1927 (based on the washed out Newfoundland postmark) and then through New Brunswick, Canada (based on the May 11, 1927 postmark) and presumably it arrived at its destination.

The cachet and Washington, DC postmark of May 1, 1928 (almost a year later) on US Stamp #628 (John Ericsson Memorial Stamps) is in line with the first flight from New York to Atlanta occurring on May 1, 1928 and appears to be a second use of that same cover again mailed to the addressee in St. John, Antigua, B.W.I., which probably explains the high value of US Postage for the time (10 cents).

I suspect the LL markings about "Washington to Richmond" and then the marking "Rail & S.S. To -->" refers to the cover having traveled by rail from Washington, DC to Richmond, VA, and from there the cover was mailed via Steamship (S.S.) to St. John, Antigua, B.W.I.

With all of the activity that cover has seen, along with the rubber stamp used for the addressee's name, leads me to believe that it was probably a philatelically contrived cover and the addressee, Max F. Berenedes, was involved in stamp and/or cover collecting in some way.

Anyway, that's my best guess.

These newsletter do not seem to be online, but if you can get hold of the Canadian Aerophilatelist Newsletter for June 2007 (Newsletter No. 71, Volume 23, No. 2, pp. 20-21) and June 2008 (Newsletter No. 75, Volume 24, No. 2, pp. 20-21) there is specific information documented on some similar Max Berendes Covers. The latter (June 2008) newsletter supposedly includes a biography on Mr. Berendes, too.

WT1,

Great information...many thanks. I will check out Mad Max as it seems like he was a philatelic machine.

what is the canadian scott number for the envelope? Anybody?
