Canon 85 mm Screw Mount

I recently purchased a Canon 85 mm Serenar F:2 screw mount and I am wondering what UV filter and cap will fit ? Anyone have an idea?

It has a 48mm thread. I also bought a 48 to 49 adapter since I have a number of other lenses that have a 49mm thread so I can share filters.
