I have to agree with everything Art has said about researching archives, photos, et al. If I were a retired Studebaker paintline worker, I could say these are the facts. I'm not. I have a totally original 1933 Rockne that is fully functional and would be a cinch to restore but I'm told "Don't, don't, don't." Restorers want to find these cars to see if the length of the stitch in the seat is correct or the grill to hood welt is stitched in first or out first. I've been in the Studebaker Drivers Club for thirty years and, from what I've seen and read, the welt should be body color. But, as someone who enjoys owning and driving--as apposed to looking at--these cars, I think the welt should be the color you want it to be. And I would hope you are able to drive it and enjoy it. 9000% of the public won't know if the welt is correct but they'll appreciate a fine car when they see it. When I bought my 51 Starlight Coupe it was very deteriorated but unmolested and the welt was detectibly body color.
