Re: Ballantine Calibrator
Two places I'd suggest would be worth a post would be the Groups.io group
Test Equipment for sale, wanted or exchange
And the Yahoo group "Manual Exchange"
I might also suggest you do a search at the Internet Archive. I've been
surprised at what I've found there.
Good luck and 73,
