I have recently acquired a Westerly Centaur that has come with the above subject. Unfortunately there is no manual with it, and i have been to the Lorenz website, which I must admit is possibly the worst website I have ever seen in my life and is all in Italian. I don't speak italian, but saw an envelope which indicated an email address. I sent them a message hoping that someone would be able to understand it, but I had it returned today by my ISP. Thanks to all responses.
