Feeling like the American Pickers here. Going thru a pole barn at a barn sale, my son Ted saw an old wheel/fender buried under a bunch of boxes, behind some sheets of plywood. Asked what it was and the person said an old cart of some kind that was missing a wheel. We moved some plywood and lift the boxes off of it. Told the person it wasn't missing a wheel, it was missing two wheels...the two wheels of the motorcycle it would have been attached to. He didn't even know it was a sidecar they had buried back in the corner. May not look like too much, but inside it was a couple of very old,thick, hard, cracked handlebar grips that said "Indian" along with some old copper oil cans with stampings that were from a company that made them in the early part of the last century. Scanning the net for antique sidecars and narrowing it down to Indian sidecars, we found that exact wheel/fender on a 1928 Indian sidecar that had a conventional passenger sidecar body. Still searching for more confirmation.
