I served my Scientific Instrument Making Apprenticeship with W F Stanley and expanded my expertise in other companies. I have manufactured, restored, bought and sold scientific instruments for 63 years and I am still active in the business. In 1976 I opened a shop in Bermondsey, London and then went on to trade in the Portobello Road, now I am only selling online. I am a founder member of the SIS Society. I am continuing my scientific instrument restoration business. Email: [email protected]
