I have a Automatica Espanola "Bufalo" 765 .32 cal that is my dad's gun (who got it from his dad (my Grandfather). My Grandfather was in WWI, not sure if that is where he picked it up or not or if it was just traded from a buddy way back then. My Grandfather told my dad the firing pin was missing. I am not sure how to determine this and not really sure if I should even try to do a test fire since it is so old now. It has a 7 round clip with it, with some really old bullets (that I will never fire). Does anyone know who makes this gun? What year it was produced? Where I can find an owners manual? Should I just take it to a gunsmith to have them look at it? Thanks for your help.
