You need photos and I believe that you are applying electric pump standards to visibles. The internals are not removed on the visibles for several reasons. They usually help to balance the weight of the pump and the handle is usually attached to the pump shaft(unless air or electrically operated). Gallon indicators are important, but not critical. Fill pipes are another story. Can be tricky. It sounds like someone has taken several pumps apart and are now missing some parts. I suggest that you take someone knowledgeable about these pumps and have then do an inventory. A few hard to find missing pieces can greatly affect the price. Dave
PS Take plenty of photos
