Hello, going through my bike stuff and came upon this chain guard and wondering what it’s worth if someone can assist please. I’ve checked sites to get an idea and I cannot find this actual guard to get an idea.
Please delete if I’m in the wrong section of this page.
thnx

$15-20 is what I'd put on it. V/r Shawn
