They’re from the phones you see in old movies that you had to crank to talk to an operator, commonly used up until the 1950’s. I put my multimeter on one and it’s still reading 1.3 volts. The owner told me I can take the whole lot of them if I want them which I’m tempted to do just because I like to collect old junk but I probably drag enough useless crap home as it is.
Are those B cells? I have an old radio that used those.
Not sure what designation they’d have… each one is 6 inches tall and about 2 1/2 inches wide
