Thanks for the help guys. I've done some more research and the gallon markers definitely point to a Canadian Wayne. I'm trying to narrow down the model and am thinking it came from a Wayne 78 or 83. Possibly from a 615 or 619 as well but the bottom looks a lot like the visibles made by Boyle-Dayton (60,70,80 series). According to Jack's book, Boyle-Dayton made the Wayne 78 and 83 under the Wayne name. Any opinions?
wocopep, were you referring to the small metal piece (marked 22450) in your post? Perhaps this piece belonged to a different model/pump than the rest?
