Wendax will get the point. After doing some research, I believe this is a Type 30.
I have attached a painting/sketch of the front of the Bugatti Coupe by Kelsch.
On both T30 and T38 cars, there is a transverse metal bar in front of the bottom of the radiator grill.
On most T30 images I find, and the sketch of the Kelsch Bugatti, there are large round objects on each end of the metal bar (perhaps friction shocks?).
On most T38 images, the round objects are no longer attached to the bar, are reduced in size, and have been moved forward several inches.
Does this logic make sense?
