I see that you posted pictures before i hit "enter".
Scalloped back boxlcok,
case colored action SxS.
Splinter forend and can't tell if it has a pistol grip on stock.
A good quality very usable bird gun (fine for occasional clay targets). Probably weighs about 6.5-7lbs. "hot" shells will rattle your teeth and be unnecessary to get the job done.
I don't remember if Saresqueta guns were considered "safe" for steel shot.
Use it.
BTW: the case coloring tends to wear/fade with handling. Don't worry about it. You can wear ligthweight leather gloves and make sure you clean it and wipe down the metal with a good quality gun oil when done (not silicone). You may also want to avoid using bug spray with DEET in it since that can disolve some gunstock finishes.
You also need to keep the parts of the action that rub/pivot against the barrels/ejectors clean and lighlty lubricated during use since they are friction points and will be most likely to show wear over time. DO NOT drench the action in oil or solvent since it can seep into the head of the stcck. A very little bit is all you need.
JMHO
