In case anyone is interested, that manifold in
Rudolph's picture in post #12 is an aluminum, Canadian "59A-type" with the number "C11A-6520" cast into it, like the NOS manifold shown below. They're still out there as I have a NOS manifold just like this one. It obviously provides a handy location to tap into the crankcase for a pre-1949 engine. DD
