604 chassis number production date

[ThanosK]

A friend offered a 604 for sale, and I am interested to find out the production date on that car. From photos, I see it has points ignition and chassis number 604A31 65670XX, I cannot make out what XX are. Anyone out there who can shed light?
Cheers

XX is just the end of the number
Normally just a single X to denote no further numbers but maybe the bloke stamping that day had the jitters and double X'd

The XX will be numbers rather than Xs. The 604 has a 7 digit serial number. That is a 1978 model for sure. Not sure of production date.

Does a car of that era have an ORGA/RP/DAM number on a sticker or plate? This gives the date of manufacture. See my post at https://www.aussiefrogs.com/forum/index.php?threads/pug-vin-decoding.146003/

Thank you, the production year (1978) wil cover us. XX meant that I couldn't read the numbers .
