List of products by brand Stanley London
British firm started by W.F. Stanley in London who produced drawing and surveying instruments. They acquired Heath in 1937 and became part of the Sime Darby group around 1977 finally stopping business in 1999.
It is probably the most replicated (or better, faked) brand with many (yellow brass) instruments being sold as 'Stanley London' 1920. These replica's are not working and are just nice paperweights in my opinion. My instruments are, as far as I can tell, genuine.
