Hi newbiedan,
We can supply the handles that you require which is part # A1851069 which is for the model 45 which was a Scott Bonnar but changed to Rover.
The Scott Bonnar sticker would be a hard on to get and maybe deejay66 will be able to point you in the right direction as he has found some in the past.
We also have parts list for the Scott Bonnar mowers in the parts list and manuals area.
