I believe that most G's in that serial # range had push button forend releases, as did other grades. A little later most had snap on forends & some guns had metal escutcheons & some had the non-metallic round Dog's Head escutcheon. Many later G's fell into this category, but they were not limited to the G's. A G in that SN range will likely have just line engraving with a little sunburst on the screw hweads etc, but they were still well made quality guns, just not highly decorated. Many had very nice wood.
