PM REDHEAD Chainsaw. Upon bankruptsy of the former IEL company was created the new PM (POWER MACHINERY) company with former employees from Vancouver, Canada. The Redhead was a very rare saw with limited production(3,600) due to the lack of power and unatractive to buyers. Later models of the WR series upgraded this saw with a more powerful engine (7HP) with a bigger bore and heavy duty gear housing. This saw is from the initial early version and very rare.
