Wow....... what a great find! and a great price!
There seems to have been a lot of people around your area that use to make wine years ago, there are none around here, amazingly.
The problem I would have with those airlocks, and I am having with the newer straight sided bubbler's versus the 3 round areas on each bubbler is FRUIT FLY"S! They can get in, then when you pull the bung out it creates a suction that draws some of the water back into the carboy.
Are those glass or plastic?
