The 1748 is a stamping and is the same or similar to German stamps from the late 1800's found on their firearms etc.
The moon appears to be a later but older addition with its outline unbroken seeming to miss any deep corrosion.
This blade also looks very much like a machete to me.
Many older blades have an iron tang with steel blade but I don't see and forged welding where the two would meet.
