@Fritillaria2
It *might* not be an antique :-) It's certainly a classic. I'm guessing it's still working, or that you are expected to work with it?
Can you get its model number and serial number?
@seachanged We work with newer ones, but even those have the bubbles (“demon bubbles” as I like to call them.)
