Thanks for the offer of tea, I'll bring the biscuits if I am ever passing.
Just to explain the comment about the bonnet...
Yes, all the Cordites / Navigators came with a flip up bonnet.
However, they could only be fitted after a large section from the front of the chassis was removed.
But in order to get the re-body inspection, the chassis must be unaltered.
So personally I'm still waiting to sort out the body before I can get a working bonnet.
I hope that makes sense, Paul.
