Not to be rude, but anything filling a 20 or 40 foot shipping container IS a big lot, but otherwise is just a prudent purchase ( Bike or 2 with spare parts) so all relative to scale I suppose.
Shooting star might have been associated with a number of bikes, but first thing comes to mind is 441 unit single or 250? Or is this an A7 or A10?
As to disposing of extras, I am afraid I dont really understand the context of the question, but perhaps I am missing something. Lets see......... stash of vintage bike parts? Just mentioning it gets most people excited and word of mouth alone could do it, mentioning on the internet forum? Local or regional Autojumble/swap meet? eBay? Craigslist in the USA.......or did I miss something?
