I'm in the process of restoring a 1929 18-36 SIN # 86078, and ran across a couple 18-36's on the web that were restored to brown paint instead of green. This has me confused as to the real colour of mine. I see no green on it other than the rad, but who knows if the rad had been changed at some point in its 80+ year life. Thoughts?

Here's a youtube vid of a brown 18-36:
