cbh65beck,
I'm NOT an appraisal expert...just a collector.
That said, I think the scales might be celluloid rather than ivory...only because there is a slight separation at the rear bolster consistent with celluloid shrinkage, and I can't make out the fine grain usually present in ivory. I could certainly be mistaken, as I'm going only from the picture.
No matter what, it is a nice knife.
Bill
P. S.
If you look along the top and bottom edges in this picture...

...you can see a little of what I mentioned.
It is VERY difficult from these pictures, and I could be mistaken...thus the appraisal suggestion, especially if you are going to sell the knife. A professional documentation
should carry weight and value.
