    Disbound, as extracted. From the Manchester City Public Library which used to hold one of the few complete sets of English Patents in the UK - the originals now mostly pulped! Complete apart from the blue paper covers which were discarded when bound. These are the full Patent listings and should not be confused with the Patent Abridgements which have been reprinted (but only up to 1930), and which contain far less information. Needless to say, these original patents are very rare. A Unique opportunity.
