Strip Dominator and M1

My buddy bought an unmodified Victor340 for 200.00. I asked for a few pictures. He was in Erie Pa checking out work being done on his duster and internet is very sketchy. He messed up and made a mistake of sending me some Strip Dominator pictures and never touching one before was shocked to see how close the plenum looked like the M1 I worked on last winter. Is the Strip Dominator ment to be a copy of the M1.
