Hi gmax, This one has got me tossed...As an owner several Scott Bonnar mowers over the years, I have not seen one like it;
but, I have some thoughts. My Scotty, which as you know I have photos on this site, is a Model 450520 which I have been informed was made in late 1974-early-1975 and if the model numbers run in sequence is an earlier model that yours, but it's not....The main differences are,other than colour, from what I can see, firstly the handle frame is straight (a 60's design), the grass deflector is fixed to the upper rail rather than adjustable as on mine (2 black knobs on top rail) and the real give away is the early Scott Bonnar logo rather than the triangular one; used up to the take over by Rover..That said, yours has the twin rail engine deck (like mine)rather than the solid used on early machines....which leads me to think that this model was made especially for some company to retail as their own product with reference to the name "Lawn King" which I personally have never heard of, or.....could it possibly be a model exported to somewhere overseas? I have never seen a blue Scotty ever.....It looks in good nick though, and would make a great restoration. Gmax, what cutting width is it, in the pics it appears to be a 14".I would hazard a guess that it was made in the late 60's or early 70's.....What a fantastic find.....and ALL complete!!
