This fascinating critter is a potato roaster for the top of a wood cook stove. I wish I had taken the camera to the fair the second time I visited, as the antique department folks had a potato there to demonstrate how it works. The tubers sit upright between the little metal dogs, against the center cone, and cook very nicely I'll bet. Too bad we don't have something like this to use today....oh, wait, we do!The kind gentleman who owns it purchased it in Long Lake. Best guesses go to Carol Williams here on the blog and Tom Cassidy and several who agreed with him on Facebook.
As I strolled through the antique and farm produce building at the fair a nice gentleman of our acquaintance presented me with an object, the likes of which I had never seen before. Mind you, when I was seven or eight, Mom and Dad opened an antique store so we grew up surrounded by cool and mysterious items of all sorts. Let's just say you can't fool me with a potato masher or a single row hand corn planter very easily. However, the best I could do with this thing was some kind of bundt cake pan or something like that. Alas, I was wrong. Let's see if you can do better than I did. Answer in the comments and at the end of the fair I will share the answer. Best guess will get credit for same.....
