Russell. I will give you a full reply on Sunday. I have owned a P1 since 1973. It underwent a full restoration between then and 1996. I have used it since then and done over 60000 miles in it. I was forced to stop using it in 2015 because the A post had become rotten again. There are photos on our forum. As I say I will send you a full run down on Sunday. I am working tomorrow.
