I agree: amazing art work done there! I couldn't pull the prices up but couldn't afford them anyway. And not interested. Who besides me is going to see them?
I nickel-plated the valve covers on the Cub more for looks than anything else. But those are exposed cylinders. And they look pretty cool! I was going to chrome plate them but was advised against that as that has a tendency to flake off; not what you want going on inside your engine. The nickel plate has held on for many years and hundreds of hours without showing any signs of wear. Your local hotrod or trucking platers should be able to do that for you.
