The stock is walnut.
The Queen Anne is a .50 caliber smooth bore without sights so it isn't very accurate beyond 35 to 40 feet.
It also had a problem with reliable ignition. Although the pan would lite, often the main powder charge wouldn't fire.
The bore extends almost all the way to the rear of the barrel ending in a flat bottomed hole. There is no breech plug in the barrel.
I studied the gun and came to realize the reason for the ignition problem was the way Pedersoli made the vent hole.
It is simply a very small hole, drilled thru the barrel wall which is very thick in that area making it very difficult for the flash from the pan to get all the way thru it without loosing a lot of its initial heat.
The small size also made it nearly impossible to get any of the main powder charge powder to work its way out thru this tiny hole.
To try to correct this I decided to enlarge the size of the vent hole so I drilled it out to 5/64". That improved things slightly but it didn't solve the problem. Even for the new .078 diameter hole, the distance the flame needed to travel was too great.
That's when I decided what was needed was a much larger hole connecting the bottom of the bore with the vent so I drilled the vent hole out and installed a vent liner.
The smallest standard vent liner has 1/4" threads on it and the design of the exterior of the barrel in that area has a large cutout to clear the lock's mainspring. That meant I couldn't use a standard liner so I made my own vent liner out of a piece of a #10-32 bolt.
Here's a picture of the area
