I think that sherlock has found the reason for the larger plate stain behind my replaced plate.
If you compare this photo with the original I posted of the plate actually on the tractor you will see the reason why it is bigger (more lines) and the rivets are in the same place as the smaller plate.
Phew Watson, i'm off to smoke a long pipe , have a relax on the violin and await the next case. "Mrs Hudson, a cup of tea straight away please!"
