I did some trading today for 2 matching side lock Spanish 20 gauges. I was told that they were made in 1967. The wood is very plain,and the pads are as hard as a rock. am hoping someone can tell me something about the maker.They are marked ARMAS URBIOLA Hns ELGOIBAR. I have posted a couple of pictures. I am sure they are not the best Spanish guns but would like feedback.
