Looks like an e-block, if so this is a transition point on stock marking and identification. Looks beech and if so the right side of the buttstock would be good to see better. In the e-block they changed how the stocks were identified, this early it should be the early method, later in the e-block it changed to a more traditional pattern (traditional in that most others used)
Little can be said with just three pictures, but it looks pretty good to me, it has the right features for a CGH/17 e-block, and CGH are pretty tough to find really nice and original (Suhl rifles are almost always well used, often abused). Generally, trends suggest CGH is the most prolific of the three, but I have found them damn difficult to acquire when I was a buyer, but either way, no Suhl rifle is common in original matching condition. They are rare in upper grades, far more difficult to find than an arsenal or WMO/DWM.
Try and do some good (direct and clear) pictures of the barreled receiver markings and the stock markings (rightside, small or wrist, and lower buttstock, also the top screw area of the buttplate) These areas will provide the information about what you have (if the bolt matches take a picture of the top and lower flat of the bolt handle stem). As Sam stated, the consortium worked by division of labor, CGH made the majority of the receivers and bolts, JPS the barrels, and VCS probably small components.. I think all finished their own stocks, though hard to say.
I have done much more trends work since this brief article, but here are the basics on the subject:
