I was curious if anyone has seen or owned one of the tall water hopper extensions that was used for the 1.5-2.5 hp engines that operated a milk cooler? I am interested in knowing if they were a 1 piece unit or if it was 2 separate pieces. I have the shorter water hopper extension that I will be putting on my LB engine that I am attaching my milker unit to but have never seen the milk cooler extension. I have attached a picture that I borrowed from the net. It almost looks like a 2-piece set-up. Wondering if it is a separate center section and then the smaller extension on top like was used on the milker engine. Thanks for any input.
