For the 7050 I looked in my hard copy 53-68 service manual...his machine was not there...then I looked at toro lookup pdf..1953-1984 modle list and specs....his machine is not there. These are my only sources of info and are for US modles. However I have found other threads about dating the same machine and it was determined that the confusion is because the newer 7050 machine was made in Canada and has diffrent serial number coding than a US machine. With this in mind..his machine may very well be an early to mid eighties machine.....but whatever the year...it's not even close to 1959.
