Hi Dick, got the info from my Pop on the paint. The brand is carried by Tru-Value hardware stores and its called "XO Rust." similar to Rustoleum. Covers good and looks all the world like the original color on the '47. I'll try to get pictures of the column he sprayed if I have time tomorrow.
Here are the colors:
Brown Steering Column color: XO Rust “Seal Brown” #146522
Taupe steering wheel taupe color is Premium Décor “Toast” PDS43 #792757
They're both made by GPM , 201 Jandus Rd. Cary, IL. 60013-2889
Looks like you can get the brown
ONLINE as well as the local store.
