Medieval Euopean Sword

[Darach]

I have an antique sword, which I am trying to identify and
classify. I have looked though "Records of the Medieval Sword'
Oakeshott E.(1991) without a great deal of success except to
conclude it seems to be possibly a Type XV in his scheme of classification.
The pommel however does not look like any of his types.
The sword is 79.5 cm. in total length, wiith a blade of 62 cm. The
crosspiece is curved and 19 cm. in length. The pommel is of
elongated octagonal section and 4 cm. wide.
It weighs 740 G. and is well balanced with the centre of gravity 1 cm down the blade from the crosspiece at the end of the ricasso. The hilt is octagonal also in section. The blade is chipped mostly at the end as if during use.
I enclose some photographs of the weapon. Can you or any of your colleagues help in identifying this artefact?
PS. I cannot upload a full picture of the sword - "Sword.jpg: File Too Large. Limits are 800 x 1280. Your file is 1021 x 254."
