Victa.ducky,
The Victa Sheerline, Four star, Cadet and Envoy are the same base (apart from 4 stroke & 2 stroke holes) and the picture is the top flap part number 8-173 according to my Victa service manual volume one.
The Sheerline and Four Star have a Victa name plate (which I have one). The Cadet and Envoy models do not have a position in the handle for a name plate.
Hope that this is of some help.
