It's double, but doesn't resemble a Rickman in any other way. It is similar (as the ad says) to an early Trackmaster, but doesn't have a built-in oil tank/backbone. Ray Hensley's original Sonicweld frames didn't have a built-in oil tank either, but I don't recall then having this frame's unusual double backbone.

all of Ray Hensley's Sonicweld frames for drysump engines had an oiltank welded into them Ray only made them for one season (1968) and then went on to do the Trackmasters starting in 1969. His first Sonicweld Triumph frames went to Nixon and were rigids... he built one Sonicweld dirttrack swingarm frame for Nixon to ride at the end of the season Louisville race of champions (that frame is in Texas) Ken Watkins continued to build Sonicwelds after he and Ray disolved their partnership this is not a Sonicweld or Trackmaster
