Need to know the age of my Mini BRASTED

[LUK48]

Hi, I bought a BRASTED Piano Miniature called MINIPIANO. I found a number in a side of a first key
(I suppose the serial number that is 1241931). Can anyone tell me the age about this Piano?
Thanks a lot!! Fabián

Numbers on keys may have meant something to the key makers, but they are rarely any use to us now. Serial numbers for Brasted are unlikely to exceed 6 digits. Have a look at pianogen.org

I don't spose it could be 12/4/1931? Just a thought...
