I had second thoughts about painting. It seems impossible for me to match whats been there over 60 years so after a light sanding to help blend the areas no longer painted with the areas still painted. I used an aluminum blacking solution used for gun parts to tone down the bare aluminum and buffed it all slightly.Finished it all with a coat of paste wax to resist further corrosion and think it looks OK. It appears a little time worn and rough but it already had some of that look (now a little more so).I feel it looks right. Thanks for all the suggestions....
