Restoring that pump will decrease its value, in my opinion.
If it had great original paint, I would agree. If it were rusty and dented, I think restoration is in order and will increase value. However, to restore or not restore was not his question.
For faces, look for Ron Scobie website. He probably had them at one time. Also call Vics 66 and Gas Pump Heaven. They may be able to help.
I can't venture a value guess without photos and more details of your restoration. Sounds like a good project though. Good luck.
