- “Publication/disclosure” will be treated as “date granted”, for now. The “Megjelent (year). évi (month) hó (day)-én (or án)”, that is “Released (month) (day), (year)”, given on the original, is seemingly always later, and we do not know which legally constitutes the patent’s being “granted”. Fortunately, filing date data is clean and simple and consistent between the data page and the original.
- the Szellemi Tulajdon Nemzeti Hivatala database in anglophone setting, choosing the Patent option, among the Advanced search on the left of the page, and using patent classification “V/h” as the keyword

- Inventor location: Budapest, Hungary
- Inventor occupation: Academic Painter (Akadémiai Festő)
(This Manó Kalisch, properly Kalisch Manó, is quite likely the "Emanuel Kalisch" we have elsewhere.)
