Looks like the bases used on RCA "Special Red" Series premium tubes from the '50s-'60s. What a great idea! Outside diameter 1.359", inside diameter 1.217", height 1.126". Nickel plated silver brass pins. Great for making your own tube adapters, test jigs, replacing broken bases on old tubes. Brand new production from China.
