regarding the accessories they are not that hard to tell apart, and throughout this thread people have tried to point out the differences in the original to the bodge/copy.
Bodge, but look at the details and commit them to memory. These crashbars are the poster child of bodge, note:
1. note the thinness and shape, this is a good first clue. it's an early '50s shape reworked to a late '60/'70s body
2. note the rear crash-bars mount to the cowls not to the frame. this will not save anything and will likely bend and rip out of the cowl.
3. note the double row leg-shield trim does not stop at the bottom but continues along the length of the floorboard. the originals were never like this.
4. most accessories were made by Ulma or Vigano, and would not have a "Vespa" or "Piaggio" shield on them.
Not Bodge, again look at the detail:
1. bars are thicker, plastic embellishment is standard for Vigano on Sprint era bikes.
2. note how the crash-bars mount to the frame at the front and rear. A bit of a pain as you have to remove them to take the cowl off, but they actually protect the cowl if you lay it down (I know, I have)
page 87 has many examples of bodge and not a bodge. Maybe we could have a moderator flag the determination for each post, but that would be a lot of work. Or we could start a wiki page...
