help with my eibar side by side please.

[JJViolette]

Hey guys and gals I recently inherited an old side by side Spanish 12ga from my grandfather.

It is an eibar 12ga side by side.

I was trying to take it apart and clean it when I noticed a few problems. The firing pin on the right side appears to be stuck as if the trigger was held down. I'm pretty sure if I put a shell in it and closed it it would fire immediately. Also I took out the two pins on the lower half and I can't get one of them back in. The mechanism inside it seems to have shifted and I can't line it up properly.
Does anyone here have one of these or know enough about shotgun maintenance and repair to help me out? I can send pics or videos, FaceTime, Skype etc if need be or I could just bring it to someone local.

I just started to take it apart but after removing a few screws and not making any progress I decided to stop so I don't mess it up. Any help is appreciated I haven't been able to find anything on the web about the gun.

The first step is to take the stock off to expose the inside of the receiver..then you will be able to assess the problem.

The second pin won't fit probably because of spring load on some of the parts inside. Take a smaller diameter punch and put it in the hole from the backside, feel around until you get it started in the hole of the parts inside. Then wiggle it around until you feel which side has the spring pressure on it. Push the internal parts in that direction until the pin will push through correctly.
