There was some uncertainty among some members weather or not the engine turning was a decal or not. 1940 Service Presentation makes it pretty clear:
Unfortunately most of the engine turning on my panels has been buffed out. I wish there was a decal replacement because as much as I'd love to have the turning done again it'd would be right out of my budget.
About 47 years ago I removed the clearcoat and re-sprayed my dash panels. I did got completely get rid of the rust but I think they are still presentable to this day. I just resprayed with clear coat in a spray can. The wood graining is my primitive attempt, done with a kit left over from doing furniture 48 years ago.
In addition to reproducing the 1940 Dash Plastic, Skip Boyer does the engine turning. His email is: email@example.com
