I probably should have kept on walking instead of stopping to look.
It was my hope that someone who read my post might be willing to help me determine some fair market values for the more popular parts but it doesn't look like that is likely to happen.
Heading back over there right now just to shoot some photos seems like it would be a big waste of my fuel and time.
I guess I will need to resort to the eBay marketplace once again in order to establish some real numbers unless something or someone can convince me otherwise.
