I've got bunches of drawers full of old bike parts. Problem is- it's too good to toss, but not worth the hassle to list and ship for the time and $ involved. Some of the stuff even has a word "campy" on it.
Can't toss that!
Faceplant (If you use it) is a good place to start. Dump all the bike trinkets out on a table and take a pic. People will (or will not) contact you. If it still sits around 6 mo later, at least you know youve tried.
Here's a local dude listing his trinkets- Do they sell? I dunno, but I've looked at the add.
Some people really get into the period correct classic stuff. 1990's builds are a thing now. Some people really want the "OE" parts for their bike.
