I have a bunch of NOS Velox kits from the late 70's or early 80's that were with all the parts a friend gave me from his closed bike repair shop, some of the tins are in poor shape from the way they were stored others look good. When I checked them out a few feel like the glue might have survived others are dry but everything else in the kits are like new still. When I get the chance I will check them out some more and add them to my pay it forward pile I have going, I'll never use them clinchers only for me.
Plus I have enough containers for my unmentionable supplies
