I'm not a member of the pump police, I say it's your pump, do it like you want. I do draw the line with porcelain pumps however. I would not change this pump from Flying A unless the porcelain was completely shot. It would be a shame to destroy good porcelain to rebrand. I also wouldn't want to keep the current green and brand it Sinclair. If you get a great deal on it, I would get it and make a trade on a 700 series Bennett with the large ad glass window and brand as Sinclair or trade for a Tokheim 39 and do it up in Shell. I sure wouldn't pass on this pump if it's a good price. And even better thing to do is get this pump, clean it up and leave it like it is, and go out and buy another pump to do up in Sinclair or Shell. Two is better than one! Brady
