Hello
It's really puzzling
The AM 10 is the same as shown in Aviation Magazine 1951

But the AM 11 shown here seems to be a two seater ,don't he ?
More ,the engine seems to be a little jet ,or are my (very new)glasses wrong?

Maybe,it's only a guess, the picture shows a "Baldo" fitted with a turbomeca in Argentina ????
