Imagine if the box was for the Victa Auto! This ones an Automatic isn't it?
It's a Model 4 chassis for sure, but that doesn't necessarily mean that it was set up as a 'Model 4 Automatic' when it left the factory. Victa apparently assembled quite a few 'Model 4 Standard' units on this chassis, to use them up after the Automatic was discontinued. The highest ODK-confirmed Auto engine serial is in the 128,000's.
The main diagnostic telltales for Automatic originality will be: 1. If there is any visible wear on the chassis lugs, from the Predicta mechanism pivot rods; 2. How the second cable hole in the carby top is plugged - and if it's there.
That's on the mower as it stands; who knows what the box o' bits might reveal...
The ODK 'master thread' on the distinguishing characteristics and serialization of the Model 4's [and incidentally Model 5's too] is this one:
