From what I've read (on this forum and other places) as the newer models came out for early 47s, those in-field were updated to the new standard. So they may have left the factory as a D-11, but if fully upgraded, uprated, whatever, they would be more equivelant to 47d22s or whatever (I'm just making up an example here).
We've got a stock example of a 47d11, not an upgraded.
You might want to just ask for a D22, but then we have an almost identical D25, so just fly that, IMO.
