I’m late to the party. Just starting on my '38 finally. Here’s the jack that was in my '38 Plymouth. One side says Auto Spec Mfg Co., St. Joseph Mich., patented July 20, 1926. Other side says No 32 Dreadnaugh Twin Lift, SJ290 bottom stamped numbers are SJ238 and the number 19. It’s the dark green color like everyone is saying. Not sure if it’s original but I suppose it will do?!
