The "Frog" is real leather but I don't think that the grips are oak; they could be rosewood or some other hardwood. I paid around £70 to £80 for it which probably isn't bad even if a fake. The one thing that made me question it's originality was it's good condition because it seems too good to be WW1. However if it's a fake, it's a very well made, top quality, fake.
