Hi there everyone, i just picked up this gem of a pump in the middle of nowhere AZ . I was wondering if anyone could tell me anything about it. I know its a Neptune L1 "belt buckle pump" but thats kinda all the info i can find. Any additional info would be greatly appreciated

I've had a few of these pumps. the belt buckles are hard to find, the rubber is not available with any suppliers that I know of, and the trim that attaches to the window is difficult to find too. The ad glass slides into the lower window trim. Great looking pumps! Brady

Any idea where i could find some decent add glass for it?

Most of the vendors sell ad glass that fits this pump if you have the factory trim work that came with the pump.
