You may well be right. I'm not sure why you are interested in the weight, but I am 71 years young and it has been less than 10 years since I acquired both the pumps that I used in my restoration. I picked up both pumps out of town and loaded them onto a trailer by myself with no more that a 2-wheeler for assistance. I disassembled and then reassembled the pump myself and that included lifting the heaviest components into place and attaching them by myself. I am confident the weight is over 200 pounds, but doubt that I could have done what I did if the total weight was 350 or 400 pounds. If I had a way to safely weigh my completed pump, I would gladly do it, but don't want to destroy my restoration. Good luck with your quest.
