Your pump is a Gilbarco 904. All of those pieces go to that pump. It looks like you are missing a few pieces that aren't pictured (does it have the other door, the other face plate, the other v-trim, I can tell the side panel was taken off, so I wonder if the ID tag is missing) and probably a few other miscellaneous parts. Whenever I buy a pump that's partially taken apart, it is inevitably missing a few other parts. The bad thing about this specific pump is the door is pretty beat up.
I would estimate the value of this pump (if it has the missing parts I mentioned) at around $700 - 750. It would be worth about $800, if the door wasn't banged up and all the parts were there.
Now if you are missing all of the parts I mentioned, I would say $450- 500, because that door will cost $150-200 (plus possible shipping) and it might take a while to find one if Tom Buckles (gas pump parts guy) doesn't have one. Not to mention the other various parts missing.
HOWEVER, those estimates are in a retail setting and it might take a while (days, weeks, months) to find the right buyer. Since this is going in an estate sale, where time is a factor I would take anything above $400 on day one and take anything above $300 on day two, especially since it is partially disassembled.
This is just my opinion. Good luck with the estate sale.
