The year 1983 is almost certainly a catalog error or misattribution — the Oesterreichisch-ungarische Bank ceased operations in 1924 following the dissolution of the Habsburg Empire and the subsequent currency partition between Austria and Hungary. No legitimate issue from this institution could carry a 1983 date. If the date field refers to a reference number, auction lot, or collection entry year rather than the note's actual date of issue, the underlying item is likely from the pre-1918 period and warrants re-examination of provenance documentation before cataloging proceeds further.
