18th Century Machete ?

[CutlassCollector]

Further to Norman's reply. This is a page from Schnitzler & Kirschbaum's catalogue of c.1850 which I copy from Boarders Away.

Note the 1700's style cutlass at the top and the 1804 pattern underneath it - makes you wonder, when we have reproductions themselves over 150 years old - also the use of cabalistic symbols on many blades.
Solingen cutlers had no qualms about including these ancient markings or the GR symbol to indicate a quality blade to the export market. I'm not sure what the numbers signify - possibly model numbers - although there are two marked 25 which are significantly different.
