It turns out that it was built by the owner of the shop called Pyramid Cycles in Leucadia, Ca. The shop was sold and is now Leucadia Cycles (great source for anything older in the Klein world...). It was identified by Jim Cunningham at CycleArt as one of several custom frames that they painted many years ago for the shop. I do not have the name of the builder or the tubing just yet, but hopefully in the next few days.
