Yeah , remember Huron Park Ontario's i volvement . The 5000 & 7000 & 65 series Pioneer / Partner were quite stout units manufactured at the Huron facility in the 80's . Still under the Electrolux umbrella . I thought the 245A was that vintage , however I see it was 70 's vintage although its reed valve (Pioneer) induction usage & chassis was close in its appearance to some of the Orange Poulans that Electolux made with the Pioneer / Partner badge (clone) during my commercial felling days . So not insane , actually a moot point since within a few years Poulan most likely , under the Poulan Beaird badge or Emersion elect.merger in 72 , was eventually taken over by Electrolux ( Pioneer) in 84 . Anyhow , as I said not a Poulan follower , Pioneer was my saw of choice , just was interested within the Canadian saw manufacturing & the morphing of Partner originally from Sweden with Pioneer & then Pioneers involvement with Poulan . So many of these saws carried similar chassis components throughout the yrs & as you stated were stand alone identities or subsidiaries of the Parent Companies . So no harm , all of these saws were very capable in there own right for their era , regardless of their origin thanks insight & clarification
