Guys.

I am in the process of refinishing a set of 15x7 cookie cutters with black paint finish that I took off of a 75 911 I parted out. My intention is to refinish them to the silver finish used in 1973 so that I can put them on my 73 911.
However, now that I have chemically removed the paint, I notice a very rough surface finish from the casting process. Did all cookie cutters have this rough finish or only the ones painted black? Were the original silver cutters machined to a smooth finish or were they simply painted silver. I have never seen an original 73 cookie cutter up close so I need some information and advice. What are my options with these wheels if I am going for the 73 OEM look? Better question: What was the 73 oem finish?

Thanks
