Of the 65 viewers of this post perhaps someone could recommend a reliable source to reply to the question.

The 59 on the block are simply casting numbers identifying that block as one in the "59" series. I have never seen any number stamped on any rear cross member.

I'm still learning this stuff, so someone else please jump in if I am wrong: The 59 on the cross member may explain why there was no quick reply. Probably no one has ever heard of such a thing. I suspect that's gotta be a mistake somehow. Or was stamped by some previous owner for unknown reasons. The 59 series blocks were used from 1946 thru 1948. And sorry to say, that's the only info the cast number on the bell housing can tell you. Those same block castings were used for Ford, Mercury and truck engines during those years.

careful, the 59A was a 221 cu. in. and 239 cu. in.parts replacement block for 1938-40 while the 59AB was the one for the postwar in 239 cu. in.. all of the 59's both A and AB had 24 studs. My sources are a trip to Thomas Edison's laboratory museum in Fort Meyers Florida and my own car. The Mercury engine alone at Don Garlits' museum all souped up like he had in his yellow Model T? I have no idea 286 cu in. 296cu.in.?? How about the black stock Mercury convertible of the post war era? The Mercury of 1939 was the first 239 cu. In but not the first 24 stud. Let's see what the ServiceBulletins shows for a chart 1938-40 page 151 begins engine. Hmmm! front cover. page 158 has a chart of compression ratio with compression pressure at various elevations in feet, I see 9 different compression ratios with no key to displacement or combustion chamber volume. At one time the judges at dragstrips had a kind of syringe that could give a displacement for test for clearly out of scope results cars. No song phrase was ever "I got a 59 block and 21A rods. My 97 carb just keeps me moving!" But you know that's the cat call for a truly in the mood flathead.

Personally I've never seen a number stamped on a rear crossmember. There are some very knowledgeable '35-'36 people who come to this site and I'm sure they would answer the question if there was an answer.
