Welcome to Oldgas.com Shop Talk, phibes. The sign does have very cool graphics. If I owned it, I would rebend the flange and display it.
Restoration or extensive touch-ups as your sign may seem to "need" can turn off many collectors from buying. I have only bought one sign that I knew was restored. It was at a major petro swap meet. A close look showed the restoration, so I passed it by when I first saw it. On the last hour of the last day I looked again. The seller said, "If you're interested, make me an offer." So I told him about my reservations about restorations and offered half of his asking price. He accepted the deal and mentioned that he was losing money but wanted to sell.
