I don't like that top sitting so high. The lower aerodynamic looking Sabre/Corvette or Corsair top would make that mower attractive and fit under shrubs better.
The flash looking white Mustang SPFC cover or the black Powerplus version used on the self propelled could be made to fit using drill screws. The base is the same.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
