My opinion is that these are Model BB (1933-1934) engine pans for 4-cylinder applications. I haven't seen any personally but they look like what I would expect and are similar to what I see in Ford parts books.
It's possible they are for a 1932 BB truck as there is some difference, which I don't know, between the 1932 truck engine pans (BB-6775/6-A) and the 1933-34 truck engine pans (BB-6775/6-C). Maybe someone else knows the difference?
Regardless, these are neat pans (at least in my opinion as a truck guy).
