Looks like a couple long rifle stocks possible , and maybe a Jaeger stock , too. In the yrs. I been messing w/ gunstocks , a good many black walnut pieces have crossed my bench , especially during the 1970's , and early 1980's. I usually gathered my own wood , and found three distinct different types of it , just enough differences to make the wood unique to the location in Pa. where it was cut. Black walnut from Pa. is my favorite Appalachian Mtn. longrifle wood. It's already black w/o all the chemicals folks use to make nice curly maple into black wood. From the Susquehanna River area , some of it has reddish to purple stripes in the grain direction. In Western Pa. , walnut from a long the Monongehela River woods , is hard , dark , and very fine grain. Sadly , my dear old Dad had a dirty , hanging above the coal bin original old longrifle stock blank cut from western Pa. walnut , back in the 1950's. Dad was a modern rifle tinkering guy , and made a double brl. shotgun stock from the longrifle blank butt stock , and a bunch of shotgun forearms for guys w/ missing forearms. What I would'a given for that old stock later in life , when I got interested in black powder m/l guns. That one would'a been in my closet. I made a discovery about walnut from central Pa. , Juanita River area wood.. Some of the wood can be long grained , with a blondish striping mixed in the grain patterns. I'm not referring to the white sapwood in the outer layers of grain , but the layers between the core center and the outer white wood. I accidently found this wood stainable with alcohol stains , like yellow , orange , and red. The stained wood looks like a dark French walnut , like I saw used on a WW1 .303 British SMLE rifle butt stock. The most amazing source of curley walnut was a huge four ft. across the stump walnut tree hit by lightning , and torn up by wind in a front yard along Penn's Creek about 10 miles up from the Susquehanna River . My friend brought his portable band sawmill to the families' front yard , and cut it into longrifle thickness slabs. The curl was top to bottom in the huge tree , and an amazing blessing to those guys wanting fancy walnut stocks. ......Sorry folks , I'm way out in the weeds on this testimony , so I'll stop. Happy walnut to all of you..oldwood
