Reference is made herein to a French filing of 28 October 1859; presumably this is a foreign filing of that.
In the Belgian filing and granting dates, "Xbre" is the month actually given.
Note: Gaz d'éclairage of French Wikipedia, and Gaz de houille of French Wikipedia; "gaz d’éclairage" seems to sporadically designate an "oil" or "gas" refined from coal, whether or not specifically applied to lighting.
In RdBdI we can find the patent in here based on the inventor's name; they are grouped in the back by the tech category. This is not an invention patent, it's a patent FOR IMPORTATION of something about a gas carburetor. Peter took photo of the entry. Not aero. Its national tech category is 5B of the Belgian system of 7/19. Not clear whether this is the aero Leveque.
Inventor location: Brussels, Brabant, Belgium
Archives numérisées of Accès aux brevets belge - Toegangen op de Belgische brevetten, p.147. section "Nrs. 8437-10167, 1860". Patents in this section of this block have both a "No. d'ordre", in this case 1680, and a "No. de l'Indicateur", in this case 10081. Beyond the antique scanned pages themselves, looking at the website's labelling of the data group, the latter seems to be definitively what we'd call the patent number. The latter patents within this scanned archive block lack "classification".
