I am 100 % sure it didnt come up with the bike when it was built. It is mounted on Favorit road bike (Czechoslovakia, something around 1970). Also, when were the sealed bearings used for the first time in bike wheel hubs ? Thanks for your help

My 84 Miyata Ridge Runner came with cartridge bearing hubs in 1984. I’ve found patents back to the 1920s but I doubt those are the first.
