Can anyone identify this vacuum?

I got this from my grandparents house, I remember my Nonno using it when I was a kid in the late 80s until he died in 2000. I would love to find out the make/model and if there is any filter available for it or at least something close I can adapt. Can't seem to find any markings on it at all.

It has a yellow top but where the paint is worn it looks like it used to be blue underneath. Still works great, just had to replace the brittle and cracked hose.

Thanks in advance!

Is it a Nilfisk?

No idea, I can't find any markings on it anywhere.

The bottom tub looks like something they put on carpet shampooers so you can see the water level.

Agreed it does. I found a vacuum parts store locally that has been around forever apparently. Going to swing by after work tomorrow and if I have any useful info I will report back.
