I just purchased this visible gas pump, but the seller was unable to tell me the make and model number of the unit. He seemed to think it was a National, but wasn't sure.
This pump is interesting, in that it also has a plate sticking out from the side, that also has a movable arrow/pointer on it. Can anybody describe what the purpose of that was, or, what used to be on it (like a label), since it was simply painted-over by a previous owner?
Any such help would be greatly appreciated!
