1936 C7 Side Window Weatherstrip question

I have a c7 6 cyl 1936 4 door. The weatherstrips are all shot. I have new run channel for the door glass, but don't know what the weather strip or wiper seal looks like. I don't know if I am describing this correctly, but it would be mounted to the outer door panel and seal junk from falling between the glass and the door. Is it a mohair lined strip like my '41 chevy? Or is it simply a rubber flap? All I see are rollers to control the window motion, but the rest is gone. Any suggestions or photos would be greatly appreciated. thanks, Tom
