Yes, this beast works like a machete and as I said/showed, the cutting edge looks awful.
Model number is one possibility but 1748 was the time of Friedrich II. from Prussia and the edged weapons of that period were different as edged weapons has been displaced by muskets and only survived as secondary weapons (except from cavalry).
I think the symbols and number are added later.
