Gerbuder Perzina Schwerin 1/M

[Sarah]

Hi, I am doing some re9on my piano and have stumbled across this page.
Can anyone point me in the direction of where I can find the age of a Piano.
The only info I can find on it is
Perzina Schweri. 1/m
Fabrik-Marke Registrirt
Gebrider Perzina
And a number stamped on the inside : 11165

Thanks

Dating a piano purely on the basis of numbers is not always as simple as it seems, but 11165 suggests that it was made around 1906.
If you are doing searches, "Gebruder" means brothers, so it might be important to sell it correctly.
