I've only seen one from that era, but best I remember it had a plain stock. Your's is probably a deluxe version. I'm only going on what I've read on several different forums, but they're supposed to be great shooters. But anyway, if the first number is in fact a G, then it would be 1950.
The one I did see was a 49 model SC, and it was pretty rough, asking price $179.
