Hello all,
I have a Crane Corwith Compeer bathroom sink that needs the pop-up drain assembly. The to activate the pop-up goes from left to right instead of up and down. Are there any pop-up drains that would fit?
Thank you.

while the actuating lever moves side to side, the mechanism still moves up and down.
so if you need just the pop-up part and not the actuating lever and the rod that goes up and down, just about any good brass assembly will work.
here is what the whole assembly looks like.

you will need keep the side to side lever, the vertical rod and the widget that connects the vertical to the horizontal rod.
something like this should work just fine. (the hole in the widget is too small to fit your vertical rod)
at least this will give you an idea of what you are dealing with

Thank you! I wasn't sure it would work!

Since it is Crane, is the operating rod exposed? Some Crane lavs have it concealed inside the overflow pipe.
