10 Years, Good thing you remembered were you put it. From the 1st rusty iron picture to the quality prep work , looks OUTSTANDING! As for Color consider museum quality - Deep Gloss Classic Black for the time period. Hand scrapes look great good job!, High polished brass, and shiny chrome. Sounds like Classic 1900s Industrial to me.
If your on a budget - Semi Gloss Black Rustoleum and Never dull polish. should look like a million bucks..
