Hi Lee,
I think you correct. For one thing my "wolf" looks far more like a sheep!
Oddly this makes the piece more attractive to me as my interest is more towards natively made pieces. In fact I wonder if the blade is even a European import? The profile, execution of the central fuller and the two small side fullers is unlike anything I've seen before from a European trade blade.
Perhaps this is a entirely native piece? I will have to review Briggs again as I recall he discussed these possibilities somewhat extensively.
Best,
Iain
