Spanish guns might be a bit heavier in that their barrels are mostly new and comparable English guns will likely have had their barrels polished out several times over a gun's useful lifespan. Certainly, guns made for heavy loads (and use) will weigh a bit more, but most of the Spanish guns I've owned or looked at were right on the money for weight, with 12s ranging from 6 1/2 to 6 3/4 lbs for a standard game gun (28-inch tubes, 15-inch LOP). The few 2-inch guns I've handled were a bit heavier than their English counterparts, and that is clearly because of wall thickness differences (not as many attorneys in the 1930s I guess)._
