Help with unknown MK marks Poland

[Fakir]

Hello,

Does anyone knows the name of this silversmith ?
His marks are MK as you can see in the pic and he was probably working in Warsaw in the 1920's.
Any help would be appreciated.

Hi,

Welcome to the Forum.

I know very little regarding regarding Polish silversmiths, but Michał Kozłowski may be a name worth looking into. Offering it only as a possible route for further research.

Thank you !
Could be the case but I read that Michał Kozłowski used to sign M.Kozlowski and that he worked until 1908.
Here, the MK stamp is from the years 1920-1931.
Is it something usual that a silversmith changes his marks ?

Hopefully another member can tell us more.
