I have massive respect for people making such detailed reproductions of inter-war cars. You guys make true historical work in my book. I know it can get especially hard with a chronic lack of reliable sources, relative lack of interest for the era, and modding being such a thankless task overall.
Also, what a story this car had. World champion in 1927, 7th place at Indy in 1929, still winning voiturette races in the late 1930s. All of that with only 4 models originally produced.
