Hello
RenzoFrom what you have said, this is an original
Victa Cortina.
Can someone explain the engine number meaning? It is 1 693 1 7 778.
Well ...
The first digit sees to be the chassis application.
It's pretty certain the 2nd and 3rd numbers are the year.
The 4th digit may be the specification change to the engine.
The remaining digits are probably the serial number ...
The source of this extract comes from the
Vintage Mowers website.
It is not an original document, but it is what I have used to make
sense of these early Victa crankcase numbers.
That the engine was stamped for the '69 year but has a Series 70 engine means
that the machine must date from the release of the 1970 mower season - that is -
From September 1, 1969.
That's my best guess at this time.
Hope this helps.----------------------
