Does anyone know this porcelain stamp?

Without a picture, you will find a wolf in rare porcelain brands. Please stop good and sharp images next time.

There you read USSR, so Russia in the Soviet period. In this case in the last third of the Soviet period.

If one continues to search as a basis with this cock, one repeatedly strikes the Soviet Union, often on Leningrad (now Saint Petersburg) and sometimes on Lomonosov-Porzellan. The porcelain brands of Lomonosov are known and accessible, yours is unfortunately not included.

So, for me, the Soviet Union is safe as a place of origin of your brand. I’m sorry, I’m not coming.

Yeah, I’m right there. Often there is no feedback from the questioner, I find it sad.

I also find the unssitte to only set pictures of the marks or puns without showing a picture of the object itself annoying. But be it, often you will be rewarded with a happy thank you and that will be motivated again.
