Large Wade and Butcher Scalloped Serrated Fixed Blade Knife

I don't really know anything useful about this knife, except that I picked it up and found it very beautiful. I'm curious about the history of the knife itself, as well as the company (read a bit about it online), as well as the knife's time period. I thought it was bone handle, but I'm starting to suspect that it might be an early plastic, like Bakelite? I haven't found any mention of Wade and Butcher making a knife like this, though - I know they made carving knives, but this knife looks like a particularly ornate, gorgeous bread-slicing implement, or else something specialized that I don't recognize. Any help would be great.
