I have one of these on Bream (curved side up.) The original (to me) was fitted some time before I bought her in 1999 and possibly over a decade earlier when the steel back cabin was fitted but needed to be replaced a couple of years ago as it had cracked. I was amazed to see that the the new one had clearly come from the same mould as it had the exact same pattern of errors on the surface. Steve NB Bream
