Auftrag nr is just order number. Last for digits is just sequence. Not sure what you mean by 419, but it is quite likely that in Mercedes nomenclature/classification US cluster is same as the St Pierre islands cluster (or South America), which number is 7.
Ubernahmetag - delivery date, yes, the Technical Manual says what is says, but the example of the version 2 data card is the US data card and it has this date.
Your order number is 77193888, so the 2, 3 and 4th digits that are showing the market are 719 and this is St Pierre. On your paint code plate you probably have 7 (market cluster).
This is what I would think. Not too many Pagodas ordered in St Pierre Et Miqquelon islands...
