I bought a mdl. 28 nos Zenith O-10355 for 1937 ~ 1942 Chevrolet from carbking to run on my 1951 216 powered 3600. It’s been a great carb. Don’t know if this helps but I’d suggest looking up carbking, his profile has a portal ( thecarburetorshop.com) his site with tons of info of the type you’re looking for.
