You have an old fabrica de armas oviedo 1904 7mm rifle wondering what the value is?

You could be looking at anywhere from $100 - $500, depending on condition. Possibly even up to $700 is it has any particularly rare markings. I'd really have to be able to see it and examine it to narrow it down more than that.

Most likely, you'd be looking more towards the central/lower end of those figures, though. Fabrica de Armas weapons had a tendency to have questionable quality control.
