Just before WII.
This shotgun was manufactured from 1990-1993 in Belgium and assembled in Portgual, "g" stood for gas operated and there was another model called the a500r. The "r" meaning recoil operated. The receiver looked similar to the a-5 model, just not so square. These guns were replaced with the Browning Gold series.
This is probably a Stevens model 520. What is your question?

square it
You cannot change square centimeter to centimeter. The square centimeter is a measure of area and the centimeter is a measure of distance.
cm square x 0.0001 = meters square
Divide by 144.
2,024 square metres = 21,786 square feet
235 square centimeters = 0.253 square feet.
Answering "How many decimal places to the right do you move to change kilometer square to meter square?"
