Ground dug bayonet - need identification

[FestungSpanien]

Hi
I found this bayonet with my metal detector in a spanish civil war battlefield and would like to know more info on it.
At first glance it seems to be of napoleonic era, but I realized that the caliber is smaller than the ones of the ancient muskets.
I see no markings at all, and some rests of blueing still remain.
Please,help me to identify it.
Many thanks for your help

It looks like a Russian Mosin-Nagant bayonet to me. The Russian M-91 and 91/30 were provided in quantity to Republican forces.

Most definately a Moisin-Nagant,from the shape of the mortise,I would say a model 1891.
