I do not know what parts are original and what has been replaced. I do know that everything was done VERY neatly. The front of both tanks are NOT dented and there are clear plastic guards on the fork tubes to help protect the tank. Both bikes have skip-tooth cranks.
I have many more photos than what I'm able to post here so if you need to see close-ups of specific areas, please send me a message.
