The Maltese cross and X means .010" undersize main bearings. I don't have the booklet handy to decode the 10,000 day calendar to tell you when it was assembled. Obviously it's a 225.

Pay close attention to the rod and main bearing sizes if/when you get that far.

Yep, .010" undersize main bearings. An original equipment blemished crank. Not that it's a big deal, but the blocks get marked in case parts need to be ordered. Are you still seeking more information?
