It is triple plated. My brother was the director of Lear Jet for Wichita and Tucson. He dealt with this company for many years and also had them chrome all the parts for his 55 Chevy. When I say I send the parts to them I actually send the parts to my brother who takes the parts in for chroming. They give him a very good deal since he has done years worth of parts with them. He is now retired and doesn't give them as much work but it sure helps me.
