Query on this.
Patrick Hogan is normally very aware of production levels.
So, how many DBs supposedly passed through this mould, in how many colours, and over what period of time?
This is a technically difficult mould? Y/N?
The answers to those questions may reveal whether moulds were replaced, etc, whether it is possible even knackered moulds continued to be used during any transitional period (ie breaking in a new mould), and if there were more than one used at a particular moment.
Just an observation....

Marcus
