Based in Lelant, near St Ives, Cornwall, I have been trading since 1979, buying and selling scientific instruments and nautical antiques. I have exhibited at the London Scientific Fair for 20 years. Over the years I have acquired many rare and wonderful items for the trade and collectors alike. I hope this continues. Mike Read. Email: email@example.com.
