Well it was pay back time Richard for pointing out a certain project accidently seen in a photo I recenly posted! HO Ho!!
About your only windscreen in the world, would it not be prudent to call by at Pilkingtons, Isle of Sheppey next time your down south and get another made from it ? With a toughened sceen, once they shatter they are gone for good. I think I would have a laminated one made and use that.
