I don't know what kind of wood it is but it's not original. The wood on it is what caught my interest. It looks unfinished of sorts. Think I might varnish it. Thinking about putting some "Ironwood Designs" buldged wood on it. The Garand wood has had a refinsh put on it and has also been repaired along next to the trigger group area. Seems like a good candidate for me to refinish the wood being that it has already been done before. I have another stock I could put on it but I'm not sure if I want to keep her yet. I have another Springfield Garand and Springfield M1A. Might make good trading material for something interesting.
The Yugo wood looks like Ironwood replacement as it is. Yugo wood is proprietary. I do not think there is "bulged" wood for a Yugo AFAIK.
Some BLO would look nice on the wood as the Yugo rifles were oil finish only.
