Thank you Bryce 👍
The horizontal nameplate was made from a strip of .020 x .188" styrene (Evergreen Scale Models part# 128). It was the very last detail I applied to the outside of the shell. It’s mounted on top of of the fluted side like the Budd prototype. As far as I could see Budd bolted these plates on the side of the car and they did not use groves on the back of the name plates.
Thank you for the feedback! Here’s a close up view.
