I'm going with decorative also. It is made to look old and used but I don't think it is or ever was a working decoy although it sorta looks like it. Are the groves that have been cut into it to replicate wings and feathers one continuous line like it was cut out with a dremell tool or can you see where a gouge was used and the lines are not continuous? A working decoy would have been made to use and the time it would have taken to cut those lines would have been used in painting or carving out another decoy to add to the spread. These are just my thoughts and opinions cause I aint holding it in my hand and having to look at pictures and like an umpire in a baseball game, you're a lot closer to plate than I am...d2
