I have never seen a top like yours and I have seen a great many Fry pumps. If you fool with Fry pumps long enough you will see so many configurations and variations that you will dumbfounded. I can send you a parts list and schematic if you like, but it will not show your cast parts. Your conduit has the early coupling which I have only seen on Fry 17s. I have never seen cast skins on the bases with the square bottom doors. Does this mean anything ? Absolutely not. LOL Good luck and let me know if you want the schematic. Dave
