1960's stall shower drain replacement to catch / trap hair

this is a replacement drain cover for a slotted one that lets all the
hair through.
3.25" bolt circle x 3 bolts. Flange is 0.15" thick. OD of flange in 3.62"
"Funky" has a custom designed pattern with a flat bottom and raised
top. My other one has round drain holes and reinforced bottom.
