Hello,

I have a Pardo S.A. shotgun with an IRU stamp in it, and have a couple of questions.

First- the number of pins and type of action. What is it, and how many pins are there?

I have numbered everything I can see that might be considered a pin. Please take a look and then list either what IS a pin or what is NOT a pin- whichever is the shorter list.



I am guessing this is a 5 pin action, but someone once said it could be a 4 pin. Yet, that was based on pictures from outside the action- like this one:




Secondly, in the following picture, am I understanding the marks in the red circles correctly to refer to 1970 [O1] and the weight of the barrels [1360]? If not, can you see anything that would be a date?

Classic 'field' SxS's are what draw me in- that way I can have more than one!
