[Bruce Lancaster]

Canada cast labels in its blocks at the front, and marked many of the blocks like 99's that are unmarked here.
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.
