This unique ATV experienced a few name and design changes. Initially it was called the Rollsport, with just 22 prototypes built by Rollsport Ltd. in North Bay, Ontario. Next it was called the Bush Machine, or Summers Bush Machine, made by E.H. Summers Manufacturing Limited just down the road from the Rollsport factory. Lastly, it would be called the Bush Swamper, or The Bristol Bush Swamper, made by Bristol Machine Works Ltd in Sudbury, Ontario.
Several surviving examples exist. If you own one of these ATV’s, please contact us here.
