Industar 50 zm39 lenses, filters and hoods

I believe the filter thread for the Industar 50 zm39 lens is 33mm.

I'd like to ask the members of this forum if this is correct and are there any filters available in this size?

Ideally multi-coated of course.

Thanks for any help anyone can provide.

Edit: Sorry, I forgot to ask about lens hoods as well, so if anyone knows about any lens hoods please let me know.

Thanks.
