There used to be a Gentleman who was myopic and would come into W&H every Saturday and stand over the Precision Paints stands and tell whoever was about that the Pre-Grouping was colour was wrong. I always assumed that he would had to have been over 80 to have seen the original in use and what with the variations mentioned above and the memory issue he was talking out of his hat. However, I was never able to discuss the matter over a pint and this, I would think, have made it much more enjoyable.
