Not so fast.....! As so eloquently explained by our illustrious friend Bruce Lancaster (RIP), see below.
"I believe the 41A was of course given the "1" designation in the parts book to indicate that it was in the 221 family, but was made with a full set of 59 cores except for the actual barrels and so retained the 59 designation. 3 1/16 59 blocks are around, but I don't know of anyone who has seen a 41 casting...hence my belief that these oddities ARE the 41A block. The "1" designation generally survived here with the 51, indicating Ford as distinguished from Merc models and parts...then in '47-8 and on into the early '50's the parts prfixes went nuts for a while."
In other words, a "factory" REPLACEMENT block for '38-'42 24-stud, 221 cu. in. engines. DD
