Normally that stock finishing data is usually accompanied by a letter code designating the laminate supplier or stock blank supplier
There seemed to be a practice of denoting the raw material supplier on key components.
The numerical sequence denotes "day week year". There is some confusion regarding the 'day' section as numbers higher than 7 have been
reported but I believe that it does represent the day of week.
I wish there was data available on those stock codes but none have surfaced to date.
Laminate codes include Bo Br Bu pha OVX NA Ha (not complete listing).
The OVX code has been identified as Weser Sperrholzwerke (Plywood works).
