Nice German strainer

[Ubaranda]

Hi all!
I have a very nice strainer made by Körner&Proll ​​in Berlin. One question - when it could be done?
Will be grateful for any hints.

Hello, any time between 1888 and the 1950ies. Don't think they were active after that. Best wishes, Bahner

Hello, Bahner!
Thanks for the quick response! Unfortunately, it is too large time interval. I will look for similar items at auctions - may be possible to determine the year of manufacture more accurately.
Best regards. Alex.
