Are you still interested in pictures of a Witcomb?
I have an orange one that I just pulled out of the basement this week to start riding again.
If you look at the the You Tube video in this thread, you'll catch a glimpse of an orange one and later, an order from Sunshine Bicycle Works, where my bike was purchased from in about 1974. I purchased it second hand in about 1976.

The clear coat is pretty much gone but for a bike that's more than 35 years old, it's in pretty good shape. ttt stem, bars, seat post, Campy cranks and sidepulls, tossed the sew up rims years ago and replaced with 700C rims.

The one thing that I hated about the bike was that if I was going really fast, probably 35mph down a hill, it would start to oscillate like crazy. Scary!

Located in Fairfax, California, Sunshine was THE center of the universe for mountain bikes in the '70s.
