I actually think the guns are quite inexpensive, wood included. I have two Silver Pigeon II combos and they had different wood finishes. The newer one had the matte oil finish and I didn't care for it so I first cleaned it Murphy's Oil Soap. The improvement was striking but I had it refinished in a glossy oil.
It's the bottom gun in this photo.
You can see the difference between the two newer guns and the three year-older one in the middle with Beretta's older oil finish.
Mine really took on a whole new character after refinishing.
The man who refinished my wood also added an extension to the pistol grip made of buffalo horn as I thought the grip was just too short.
Overall, they are darned hard to beat!
