Someone says this is called a three tube bottom bracket? The tubing is thicker then it looks in the photos because of the overall size of the frame. All the main tubing measures a very clear 1.25". Looks repainted.
I can take some more detailed photos this week. It was a busy bicycle weekend and nice to spend time inside and out of the rain tinkering on something different. With that said, something different is also something hard to find, and with a broken bearing cup that is a slightly odd size, I'm now searching for alternatives as a replacement to be able to build this frame up and ride it!
