Qualcast Classic Suffolk Punch 43s Self propelled petrol cylinder mower

Qualcast Classic Suffolk Punch 43s Self propelled petrol cylinder mower in working order see video as you can see in the video the blades had surface rust but ive now ground all of that off with my grinder and given them a coat of hycote has been maintained every year, last time used was last year but dad now too frail to use it so got him a flymo, could do with oil change as he's not had it done this year but runs great, grass box is not original and dont know if it sits right, little rust spots here or there nothing major.
