I've restored many pumps over the years and the shine has become old to me and now I'm cleaning them and lightly blocking them 600 then sealing with clear satin. But if you want to restore it, you'll have fun and be careful, one leads to another. Again that pump would be a great candidate to clean and seal in my opinion.
It appears to have started blue - west coast maybe Richfield - red lots of others.
Try gaspumpheaven,com on line. As for the nozzle I'm sure others will pipe in on that. You may have to fabricate your access doors but I'm not sure what they look like. Additional pics may help.
