Seconded. This is the only one I've seen too. I scoured the web to find another and could not. As you mentioned this 15th Duck Stamp knife is also seen with a bone stag handle. So that's three different bone handle variations all with serial numbers. This was number 1267. Right in the middle of the production run. The rivets etc on this blonde example seem legit Schrade factory construction to me too. The flyer for this one obviously doesn't tell the whole story.
