This F13 has English-language instruments and was intended for John Larsen Aircraft in the USA as a JL-6, but seized by the Allied Control Commission in Germany and given to France in early 1921. It was already listed in the Musée de l'Air catalogue of 1922-23. Construction number 609 is apparently confirmed on an airframe part and it is not c/n 600 which was put to use in Belgium as a racing pigeon transport.
