Replying to Russian 50mm prime lens

Hey guys, I've read in a thread pretty recently about a lens and I was interested in it, but I couldn't remember the brand to save my life.

I'm 95% sure it's a russian brand, and it's based on a zeiss model. It's a 50mm and I'm pretty sure it's a f/1.8. I think it's a old lens too.

It was a cheap lens but it had amazing bokeh and was really nice for the price.

Thanks and +k for any kind of help
