Nice finds. Pumps didn't always have plates on both sides, especially if they were farm pumps or rebranded from a brand that didn't use plates at all. Doors got changed over the years and other factors might determine whether a door had a plate on it or not. The Shamrock plate is probably original as the pump looks like it is in original condition. Not sure that plate was ever reproduced but it may have been. As far as collectibility goes, both pumps are common but desirable with the Wayne 70 probably more so than the Bennett. Good solid pumps are getting harder to find every day......GB
