I have a Boss pump as shown in the photo. It has 118 4" cups with 4" connectors or about 78 feet in total length. As far as I can tell the only thing missing from the original is the wooden handle on the crank. It has the patents listed on the 8oz buckets as 1902. There are other patents listed on the chain dated 1893. I am interested in selling the entire system. I can send photos if interested.
