Where is this hallmark coming from ?

[Martin Lubojacky]

Thank you all for your inputs. Coincidentally, I also received some reaction from experienced colleague from the Czech Army Museum in Prague, this morning.

So, he says:
Based purely on the construction of the blade: Time of producrtion between 1750 and 1830 (I think that also the style of the engraving corresponds to this age). In any case it is European blade, very probably one of that time German states or Switzerland, but Russia cannot be excluded (since Russian sabers had similar features like Prussian ones). In no case French or Austrian. Very probably made as infantry sabre for grenadiers or sappers. They did not comment the engraved bird. Their opinion is close-out sale of old stock form Europe to "third markets".

Just to add: I was really very surprised by the quality of the blade. Despite the signs of long time practical use, despite the long time in Africa, the blade is still, nearly obsolutely, straight and springy (also light). And the steel is,I would say, relatively hard in comparision with other blades I have seen.

Jim I recall that thread and went in after this one ... I wonder is it Hungarian....?

The bird is similar...although it is remembered that it is Mythical and could vary in form and artists impression. The foliage represents the upper world and the Turul perches on top of it. See also https://en.wikipedia.org/wiki/Turul
