Kaskara with a peculiar maker mark

[Mauro]

unfortunately this sword had no scabbard but I decideed to buy anyway due to the peculiarity of the blade and the maker mark. Many thanks for the various contributions. I have other kaskara in my collection (and I shall post another one very soon) but I have not seen other guards like this, that looks hand made and that, to my eyes could indicate an old age. However the proposed approximate age around 1870 or slightly younger seems to me a quite good approximation for the blade and probably also for the mount. Thanks again to all the contributors
