I've been studying up on radiator issues and found the 1930 service bulletin on radiator baffles posted in another topic here. Others may find this useful. It is about the 5th or 6th post from the top in this topic:

I'm a relatively new Model-A owner and a very new (about an hour) member of The Ford Barn. I found this five-year-old topic via a Google search. I'm just writing to say thank you for helping me learn about the baffle in my radiator.
