I am needing help with the value of a STANDARD OIL GAS VISIBLE PUMP. I have a chance to purchase this pump and needed to know approximate market value today.

No such thing as a "standard oil gas visible pump". What you have there is a Wayne 515. Looks like it may be missing the pump mech...I'd check to make sure. Otherwise, it's missing a few parts but looks like the glass is good. IF the mech is in there and only missing the pieces visible from the pictures, and IF the glass is good, I'd say $1400 more or less is a good place to be on it (without the globe). Has a cool look to it.
