G'day wce,

This Victa Special is a bitsa,it's from around 1959 to 1961 ,the engine number is from an earlier Victa Special.

This mower never had auto flaps the base does not have the alloy extensions to hold the flaps in but
someone has installed the earlier axle locator brackets with the extensions for the flaps.

There are 2 types of auto badges ,the earlier badge is smooth alloy around the Victa Automatic
the other badge has a rough texture on the plate.

Because this base has no edger slot it is the last of the Victa 18 alloy base mowers sold.
