Based on Belgian original filed 17 February 1911.
See also Patent FR-1912-440150, with similar dates all around. Actually the filing date given of 14 February 1911 is clearly a mistake, since the Belgian patent (17 February 1911) must have been filed earlier and since the other patent was filed on 14 February 1912.
