I have a JOY MFG pre-visible gas pump and know nothing about it. Can someone tell me if it's rare and exceptional. I retrieved it from an old mine sight in California. Dates back to early 1900's. In great shape, considering. Porcelain dial on back is wiped out but front one is perfect. Crank turns still. May consider selling if the price is right. Please email me at 'firstname.lastname@example.org" for photos.
Thanks in advance for information.
