Primarily Petroliana Shop Talk Forums Shop Talk Petroliana Forums Petroliana Value Questions Need help with value on this early visible pump

I want to make a fair offer on this , I haven;t seen it in person yet. I don't even know where to start . I have no experience with visibles, I'm guessing it's an early Fry Mae West and with all the rust maybe 1600 on the high side. But I could be way off, and the mechanism on the outside is something I've never seen and can't find any reference to. Thanks , Tom
