G'day Andrew
You speak wisely, young sage ... laugh
I am embarrassed.

The surprise for me - in looking at this - was the change in
carby on the last examples of this model. The move from the original
Vacu-jet to a Pulsa-jet is something I will note from now on.

There is another surprise too - that the Model 40 was also fitted
with a Briggs 6 Series in its final years!

Yep, there is so much misinformation and obfuscation out there.

Many thanks
