ETKA shows this:
CDUD: 6/12-
CPNB: 5/13-
CTBA: 11/13-
CTBC: 1/14-
All of these engines are "open ended" with regards to date codes, and don't show any specific sales region.
The CCWA shows 11/08-9/12, so it looks like that engine is no longer in use. But ETKA has been known to have mistakes. There should be a sticker on the top of your engine, just pop the top cover off.
