Patent FR-1903-337676

Here we have an FR 6.3 original brevet with an FR 6.4 addition. In this particular case, at this point in the evolution of French patent classification, “aérostats” and implicitly other aero-material are specifically included within FR 6.3. That is, this is not a case in which a non-FR 6.4 designation is used to non-aero applicability of the patent.
