So j started breaking this down and a few bolts inside I can't undo leaving very little non cast aluminum inside but still a little bit of odds and end components. It looked so clean inside j wonder now if someone wouldn't have rebuilt it but I screwed it up now :/ I had never seen one dismantled though but it was a Beautiful piece of work! I feel no matter what I'm going to get the lower end of all the scrap I have right now but I'm hoping there is a dirty cast aluminum category or somethjng
