I picked up a nice 12 ga lifter yesterday. Serial number 11009. It is a light weight. The unstruck barrels weigh 3 lb 11 oz. I am trying to square this up with the stamps on the flats. I see a 4 where I would expect to see unstruck barrel weight and then over to the
left of it a 13. Does anyone know how I should interpret this? The 30" barrels are uncut and the thinnest spot is .040 so there is not much if any missing.

The other thing I am pondering is the frame size. There is no stamp on the foot of the rear lug to indicate. There is what may be a 1 stamped on curve of the second lug. Measuring shows 1 1/16" between pins so I figure a #1 frame. Then I take some other measurements and from the chart in the serialization book page 45 it looks more like a 1/2 frame. All the other frame measurements are exact for a 1/2 frame size. There is some case color on the frame yet and all the eges and features are nice and sharp so it has not been overpolished. Isn't this gun much too early for a 1/2 frame?
