The Gambles dept store used Murrays and other manufacturers as their branded bikes. They are the same as the other bikes made by Murray as that one for sale is, just branded as Hiawatha. The model name was also unique for those bikes, like this one, Hiawatha Penetrator III.
Even though that bike looks like it's in decents shape, nothing bent, the price is way over what it should be IMO. In pristine condition might be worth that much.
