Wilton WRP Mallad Duck Carving Set

I know this is made by Wilton- I can see that on the blade. However, what baffles me is I can not find these anywhere online! I can't find any information about when they were made, what they are worth, etc. This carving set looks like the kind of thing Bruce Fox would make, but I think he usually marks his work and a lot of his pieces were made in Germany (at least the blade). My blade clearly states RWP Wilton Company Made in USA Stainless. Anyone have any information about this mallard duck carving set? I would love to know!
Thanks!
