Needed this sled like I need an insulator, but there it was...couldn't resist. ( yeah I know the 141 and postal 210 probably aren't power...) Couldn't believe the craftsmanship in the sled though. We call 'em moose sleds up here. ( for hauling dead moose out, not for hooking up to them and going for a ride) Still has old hemp pull rope. Most of them have solid sides. This one has 3/4" oak or ash steam bent to a THREE INCH RADIUS!!! not impressed? try it! Then the runner rails appear to be reused wagon wheel rims ( try saying that three times fast). Shelves come right off just in case...
