Tom,
The bike looks great. :thumbsup: It is worth $1500-$2500 as is, and I would lean towards the higher price since it runs.
From the photos, I think that someone started to restore the bike, but gave up and just put it back together.
1. There is no paint on the coil bracket or the cylinder head engine mounts and they should be painted black to match the frame.
2. The top of the triple tree is smooth painted and it should be a black wrinkle finish.
3. The side cases on the engine are supposed to be black wrinkle finish.(The engine paint is available from any Harley dealer.)
4. The air cleaner is upside down. Look at the outside of the housing and turn the housing until the little vent hole is facing down.
5. What is the finish on the rims? Most people paint or powder them silver but they are supposed to be zinc plated.
6. The seat is not correct for the bike. It may just be the incorrect seat cover.
7. The taillight lense should not have the chrome trim ring.
8. The rear brake rod and all of the small hardware parts should be zinc plated.
Overall, I think that you found a jewel. Get a hold of a service manual and a parts book. Here are some links for parts.
