48th week - 83rd year.
Those older units had a bunch of extraneous numbers before they got to the good stuff. Then the current dating system applies – 1st two numbers are the week, 2nd two are the year.
At least, that’s what I have in some old manuals from that era.
ANSI probably approved that series in 1982. But if you’re not sure of the date the ANSI is close, usually.
Not 100% sure but I would go with 1983.

Thank you gentlemen for the info.
