A very useful summary!
My 'Habicht' 12 bore boxlock non-ejector was made (maker unknown) with sling swivels and a big cheekpiece for the Austrian market in 1964. It has a Greener crossbolt and a bit of basic engraving. The 27.5" barrels weigh 1350 grams, with a total weight of only 6 lbs 12 oz. Chokes were Modified and Full, now opened out by me somewhat.

The stock is completely straight, like a rifle, with no cast, which explains why I hit so little with it in my earlier years.
