Looking for name of door trim part

Question

I have an old door with what looks like a wooden equivalent to weatherstripping. The door, and frame have mating parts that interlock. I'm trying to figure out what its called, to have a chance at replacing a segment. Any direction would help (even a better search term)

Frame side

Answer 1

Usually this stuff is metal, known as "interlocking weatherstrip", but since that's not a great search term, it's often found in the same vicinity as "spring bronze weatherstripping". Check kilianhardware.com, under the springbronze tab.
