Unmarked 7.62mm x 54mm

Is there any way to identify the origin of this unmarked 7.62mm? I am wondering whether it might be Spanish during the Spanish Civil War. The bullet is non-magnetic but I’m afraid that is all the additional information I can offer.

Jim, in my files it is attributed to Spain.
But I have no date for it.

Thank you Alex. Municion.org show a couple of very similar rounds as ‘Spanish Civil War’, I’m thinking a Spanish-based site would probably know.

And as we are on it, Spain has some interesting variants in 7.62x54R!

It seems made in Spain for Republican Army.

Thank you Pedro.
