Anyone else seen a MkIII engine stamped here?

I wonder if anyone else has ever seen an 850 Commando MkIII engine stamped on that nice flat block just below the timing side crank nose?



I'm not positive that I've stamped EVERY Commando engine that I've overhauled, but I have stamped a few with "BAB ##/##" (month/year).

Anyone have stamping on your bikes?

Found one, Chip's bike I overhauled in '08...
