OK, while we're waiting, I'll hazard a guess.
My guess is that it is the only known example of an extremely rare vise cast by the short-lived Eskimo company "Fire Wolf Foundry." An Inuit native named Agloolik became weary of hunting and fishing for a living, and always yearned to try his hand at the mechanical arts.
After studying the articles in his subscription to Popular Mechanics (which had to be delivered by dogsled, as Agloolik was miles beyond regular postal delivery routes), he decided to build a foundry and create the only American-made vises ever to be manufactured in Alaska. However, this being his first venture of the kind, he forgot to put the company name on the original pattern, which meant that it was not transferred to the molds.
Unfortunately, Agloolik had not considered that an iron foundry might not be an industry that was well suited to operating on ice floes, and as soon as the first ladle of iron was poured into the mold, the whole factory melted through the ice and disappeared into the frigid waters below.
Only one vise is ever known to have been recovered from the ill-fated Fire Wolf Foundry. A National Geographic expedition surveying the area picked up an odd sonar signal, prepared a team of divers to descend into the perilous waters, and found the wayward vise - yet unmarked due to Agloolik's oversight.
The vise was ensconced in the National Vise Museum in Reykjavik, Iceland, where it delighted museum-goers for decades. However, after an epic flood due to snowmelt caused by global warming, the vise was lost, along with the other two displays in the museum. Until NOW! Now it has shown up on eBay, a one of a kind testimony to Eskimo ingenuity, and rare beyond all description. Bid now, bid high, there won't be another one like this!
And THAT is my guess.
