Carb Question, please identify

That is a 1945 model, i could not tell you what year it seems to be missing some stuff i have on the one in the garage. You could make it work but i have heard the 1920 would be a better carb. Someone else could probly elaberate alot more as my expertice is not with the one barrel carbs!
I also don't like the fact it looks like it has been spray painted silver....
