Evening All,
On a Mark 1 we have the standard profile with the raised lip but Mark 1s' generally have a SS cover strip which is fixed with bronze pins that are roved over.
You do not remove this cover strip unless you really really have to!
Mark 1's do have scupper slots, 2 or 3 per side, as a feature.
We don't have to worry about timber toe rails, another reason to have a Mark 1!
Phillip.
PS. All pray now for a NE'er late next week or early the week after!
