Sorry to bother you alI I have a spanish side by side 12g shotgun . It's quite old and I cant find a make . When I am out in the field it miss fires a lot on the right hand barrel, so I sent it off to the shop who I brought it off as it was a snapped pin , since being back out with it the issue was still happening . So today I have looked at the pins my self and he hasn't changed it at all as the pin is snapped still on the right as before .
Can you help me out on how measure it so I could buy a replacement. Or has any one seen one like this before .
