I have an old revolver that was at one time my grandfathers, when he passed it was given to me. I am not really into older guns and have not been able to find much info about it, anything that anyone could tell me would be great. The gun is marked on the top of the barrel with Retolaza Arizmendi, Eibar Spain. It also states 38 long cartridge on the side of the barrel. I will try to get some pics up if possible. Just wondering what I have and if it is worth anything (to the point it should be insured as a collectable or anything) thanks for any help you may have.
