Hi Cary,
Values are such a subjective issue, I'll offer my opinion based on what is visible. Also, values are based on several other factors, are you buying or selling. My opinion is just that, may not be accurate in your neck of the woods.
The first pump is a Bennett 900 series that is missing all the trim and faces, this could be just a parts pump. It's missing approx. $350 in parts. If it was complete and nice shape, they sell in the $700 and $800 range, you can go from there.
The second pump is a Bowser 575, looks fairly complete, maybe missing some trim, again these are somewhere around $800 retail.
The third pump is a Neptune 855 and it's missing some critical parts which are hard to find, I call this one a parts pump only. If the nozzle receiver is broken as they usually are, then that really hurts. I only see a few hundred in sellable parts, not all pieces are in high demand.
The forth pump looks like an Erie clockface that has been cut down for a farm pump, not exactly sure what it is. Little value, maybe a hundred or so.
It's really hard to put values on a pump without seeing it in person, so please take my response with consideration of all the factors I mentioned and some that I forgot.....lol
