Found one!!!

The King George VI post box in Penzance...the oldest allegedly in the town, painted gold to commemorate the Gold medal won by Helen Glover by winning GB's first ever Olympic women's rowing gold.

So we had to do the 'tourist thing' and B posed next to it...as if it might 'rub off', or to show that we did actually have something to do with it! Well, I suppose we're British, is that enough?

Having found one, it was quite nice that is was a George VI version...also being a bit 'lop-sided' was fun!
