There are no markings anywhere in shower to identify it. It's original probably mid 90s. I'm looking for a replacement for this drain rail. I don't think it ever had a plastic or rubber sweep.

Hm... You probably would be able to attach a drip rail with a sweep like the 10-325, but you might need to drill new screwholes. How's that sound?
