Blazon: Sable a lion rampant double-queued or bearing between the front paws an escutcheon gules a fess argent (Austria)
The lion is a reference to the arms of the Habsburgs, and the escutcheon is easily recognizable as the arms of Austria. The region was under Austrian control until 1806. It is possible that this grant of arms was part of an ongoing power struggle between the local lords and the counts in Scheer; the grant may have been a show of support for the lords from Emperor Leopold I.
