Was pointed to this site by an article in the Sunday Papers. Put simply, an enormous collection of manufacturers user guides and manuals for a vast range of products and items. From household and leisure to vehicles. Very comprehensive and all free download. Great if you've lost a guide or bought something without one.
Had a quick look at the Pentax range and it just goes on and on. Cameras, flashes, range-finders. You name it and it's probably there. No doubt I'll be proved wrong on that one
