Cuba 1928 - SCADTA "REGISTERED" First Flight Cover from Cuba to the USA.
First Flight cover from Cuba to New Jersey, USA, flown by Captain Fritz W. Hammer. Franked with a 1923 Colombia, 20 centavos SCADTA stamp overprinted with a dark gray 7mm "C" (for Cuba) and a red 13mm "R" (for Registered) plus a 2 centavos red Maximo Gomez Cuba stamp. As it is always the case with these SCADTA covers mailed from foreign countries, the official stamp from the country of origin remained uncancelled by SCADTA. The SCADTA Consular overprinted stamp was cancelled with a three-line "Via First Air Mail - COLUMBIAN PATHFINDERS" handstamp applied in black. (These overprited stamps are described as "Consular" since they were sold at the Colombian Embassies of the respective countries for use on airmail carried by SCADTA). Only 50 of these 20 centavos Colombia SCADTA Registered (Correo Registrado) stamps were ever overprinted. The stamp on this cover is missing a part of the marginal paper at the upper right corner and has a piece of the adjacent stamp attached at the lower left corner.
As far as the circumstances surrounding this Columbian Pathfinders First Flight, I have been unable to find much information, only that they were flown by Captain Fritz W. Hammer and that only about 8 covers exist. Found some information on Keystone Pathfinder airplanes but these, as far as I. can tell, were never used by SCADTA. SCADTA was using Dornier airplanes
AN EXTREMELY RARE FIRST FLIGHT COVER, priced taking into account the faulty SCADTA stamp
