Words or phrases, like "TOC", pre-war, lightweight, track bike, cruiser, etc, etc. Are generally used when exact year , or possibly even maker of machine in question is unknown! That's OK, but, Personally prefer , " unrestored", original paint, one family owner, or even rusty, is good, tho, for sale is the best! I will look at anything even remotely old with those descriptive words! Because, to get the good stuff ya gotta Look!. And look, and look,,,,,,,,,,,
