U.S. Army Air Corps goodwill visit Europe 1930 - info request

[Arvo L. V.]

Esteemed forum members;

I understand that in June/July of 1930, a number of U.S. Army Air Corps Curtiss Wright aircraft undertook a goodwill tour to a few European cities. On 22 June 1930, three U.S. Army Air Corps Curtiss Wright fighters visited Tallinn, Estonia, as a part of a larger European tour. To date, I have not been able to locate any additional details re this event. If I can be pointed in the right direction to locate the following information, I would be most thankful:

- What were the exact dates of the 1930 goodwill tour and which European cities were visited?
- How did the U.S. airplanes reach Europe from the United States?
- Which specific Curtiss Wright a/c were used for this tour?
- Which U.S. Army Air Corps squadron did the aircraft belong to?
- Do photographs exist, showing the aircraft in question - as they appeared on their goodwill tour?

Thank you very much in advance.

Regards;
