This belongs to my friend Ted, and he asked me to list it for him. What the heck is this stuff? I grew up in the burbs, so I have no earthly idea as to the inner-workings of a milking device; however, based on my limited knowledge of cows, some things just seem like they'd be "logical". From what I've read, the item is a Babson Brothers surge milker.
Rumor has it that the other parts are inflator cups and a check valve. There's also some other part there as well. Seems like you may need a pump and you'll be off to the races!
Lots of pictures to demonstrate condition of product. It is not PMA'd or STC'd. All joking aside, it seems like it's in good condition.
Have a peek and message me with any questions.
