Up for sale here is this NOS box of 100 blind rivets, dated 1974 and Made in USA.  These are really nice, and were originally used for some sort of weapons system.  If you google "Blind Rivet DSA500" there's an old government communication online that talks a little about them.  This is a really neat item!  There are indeed 100 rivets here--I counted 100 plus one extra half-rivet.  Please see my pictures for details.

US shipping and handling is $10, and international is $36. If you have any questions, please ask.

I have lots of vintage electronics listed--feel free to take a look!
