Who made Sport 22 Long Rifle single shot bolt action?

Without a lot of luck, and a lot more information, this may not be possible to answer. Sport is not a well known "house" brand, such as J C Higgins, Westernfield or Revelation. It could have been made by any of a number of companies that would relabel their guns to a "store" brand, and does not appear in my cross reference lists- and single shot ,22 bolt actions are very prolific.
