Hi Dick, after further research, I found that a bronze shoe was an optional extra and that the remains of what I thought was was a GRP botch up, was in fact the original shoe in GRP which had been constantly repaired, due to taking the ground when driving up beaches. The bronze shoe which was originally made by Irons Brothers in Cornwall is no longer available (they disposed of the original mould when G W Parker closed down). If any one now wants to have a Bronze shoe, which is obviously much more durable, I have a mould which I made, available to borrow, and only requires a little additional filling and fairing (about 12mm on the upper edge) when fitted, due to shrinkage of the bronze in casting. I used Fabril which is a GRP filler paste. I also cross drilled and put in two 8mm Dia bronze rods peened over at each end to make sure it doesn't fall off, having first drilled two oversize holes and filled them with epoxy so that the wooden core is not water compromised. I can recommend E&D Engineering and Development, in Lyminton, who cast the shoe for me and only charged £136 including VAT and delivery. They normally do a bronze cast once a week but I was fortunate that they had a four day run of bronze pouring to do, so having posted the mould to them on saturday, they had it on monday, poured the mould on tuesday and after cleaning up the casting, got it out to me by Fedex on friday and I received it on monday midday and had it fitted that afternoon, including antifouling.
