Vintage Folk Art Oriole, Signed H. Sloan, Maine rose design I assume this cool hand

I assume this cool hand carved propeller once attached to what would have been quite a large model airplane

It is deeply and beautifully carved

toning and stains as evident and a small tear at lower left corner

with squarish links that very much show the hand--or blade

The caliper pulls all of the way out

Vintage Folk Art Oriole, Signed H. Sloan, Maine rose design I assume this cool handThis is one of six carved and painted birds I found together, all signed H. Sloan, Maine, and I believe dating to the 1980s or so. I've found a few other birds signed by Sloan out there on the internet, but haven't been able to dig up anything about him, and don't have a first name. Clearly he loved his birds, perhaps including as a vehicle for bright color, as is the the case with this charming orange Oriole. 5 3 8" long measured beak to tail; 3 3 8"
