The ratings page is part of the licence of which the CAA should hold a record. Around 2008 the CAA were converting all their Microfiche records to pdf format. This was part of a government requirement for Electronic Record Management. I also recall from my days of Air Law that the requirement to retain a log book was for 5 years from the date of the last entry. Art 235 now specifies 2 years from the date of the last entry. The 13 month stamp was merely a certificate of revalidation and did not constitute a ratings page.
In 1995 a PPL would have included all ratings in Section XII of the licence. Typically, single engine aeroplanes (self launching motor gliders) and single engine aeroplanes (landplanes) with weights not exceeding 5700 Kgs. + night, imc etc.
The requirement for the holder to retain a licence simply says for a reasonable period Art 235 however; the CAA has a responsibility to retain details of all licences it has issued.
