It's hard to say for sure. Most likely yes, they are custom shop grips. Probably a more recent pair and made from exotic wood by an overseas supplier. I base that on the wood grain and finish plus the use of the custom shop medallions that are in it. Those medallions are not readily available outside of the CS.
DFW would be able to confirm or rebut this, let's hope he comes by this.
