The US edition of this patent explicitly identifies filings of this invention:

Patent family descending from Patent FR-1885-168266

This patent could be identified by several numbers. (We don't yet have a fully worked out method of referring to Italian patents from before 1902.) It is number 273 in a sequential list of patents granted in the second trimester of 1885. It is also identified as number 213 in volume 36; and as number 18289 in the general register. This last is probably the closest to an overall serial number and the best one to use for our purposes here.

From Italian patent data set

In Marco M's dataset patent 18289 shows up with this information:

  • 1887 41/485 18289 20956 v generatori di vapore motori macchine diverse ed organi delle macchine Perfectionnements apportés aux aux chaudières multitubulaires a tubes amovibles. Perfectionnements apportés aux aux chaudières multitubulaires a tubes amovibles. O Société Anonyme cooperative pour la construction de chaudières inexplosibles 15 Paris France France
  • That may be the same patent substantively, but it's listed as 1887, tech type 'v', and the title suggest it's a steam engine. Perhaps in 1887 it was sold to the SA construction de chaudières inexplosibles? which means . . . "inoperable boilers"? More likely it's a different patent, but I can't see why it doesn't match.
