Tony, you are absolutely right. Those are from the Ford Vedette, before Ford sold out to Simca. I have one that will go on my '40 engine when I get around to finishing it. Also, the Simca Vedette aluminum crankcase with steel oil pan will bolt up to the '40 block just fine if you use a Simca oil pump or modify the pan. Have one of those too. Nicest piece is the Ford aluminum pan that you refer to.
