Got scans from ‘Skyways’ (28 October 93) last night.
Here is TNCA 4-E “Quetzacoatl”
(sorry – poor quality) 🙁

Thanks Wieesso, you know Ralph O’Neill was one of the factors in the demise of the Mexican aircraft industry, while some people in mexico favoured mexican designs Ralph O’Neill favoured foreign aircraft Ralph O’Neill was an american and mexican citizen however he was an aviator and flew for the US armed forces in Europe during WWI, so his ill advise and anti Lascurain`s aircraft attitude was in part one of the factors that caused the demise and disappereance of the early 1920-1940s mexican aircraft industry .

Ralph O’Neill had dual citizenship however had a special favour for american aircraft designs, this ended in the Azcarate Corsair a design licensed from Vought, this caused that the TNCA`s later designs were not supported by the mexican air force
