I was messing around in the garage and found this WWII relay in a can! Sorely tempted to take a can opener to it, but maybe somebody needs an R-67 relay to fix an old war relic? So instead I put it on Etsy; https://www.etsy.com/listing/1396083064/wwii-relay-in-a-can-never-opened
I just wish shipping costs weren’t so high; I discounted the shipping to $4 but it all adds up the same.
