To the best of my knowledge this is an all original 1939 Olds. I believe it was called a business coupe. The only thing that has been replaced is a custom made timing chain 2 years ago. It starts, runs, drives, and stops. Still have original certificate of title from 1939. Sounds as smooth as a sewing machine when running. The only thing that needs fixed is the lower radiator hose. When my dad replaced the timing chain, he didn't get the lower hose on correctly. He died before he could fix it. It even includes the original certificate of title.
