Rear spacing is 120.65mm. The hub and wheel are not original. I do not know the threading of the bottom bracket. What do I need to do to figure that out? I have uploaded more photos with closeups of all the lugs. I noticed on the head that under the paint there is an outline of the letters W and B. Not sure if that was an old sticker or a logo that came with the bike originally. There are also some letters KGF (or CGF?) on the bottom bracket portion of the frame.
