Thanks, Stik! I've looked at quite a few aerial photos of airfields, most of which are taken from such an altitude that about all I can say is "that's an airfield". I look at the photo above and go "Is that snow on the ground? Can I see any striping? Is that just snow that's been piled up along the edge that looks kinda like striping?" Kinda what I've been running into recently.

PS> A follow-up. After perusing a couple of WWII videos of air operations, I have to say that I now believe that there is no information on striping because there was none. In these two videos, I have looked for evidence of striping on the airfields, and have seen nothing that looks like it. I'll continue searching, but at the moment, I don't think the runways were actually striped. Why waste the paint, I guess?
