SilverCrest 1770 A1 espresso machine grinder parts

[Alekbgd]

Hello,

I am new to this forum and I need help ...

I have espresso machine SilverCrest 1770 A1 model.

I need upper burr for integrated grinder on this machine...

Does anyone know where I can find it or does this upper burr fits from some other espresso machine similar to this one that I have?

I attached picture .

Thanks in advance.
