I also keep photocopies of the most important pages. I dont know wether its just me but the CAA havn't ever stamped my book
On the pages that ive completed skill tests, the only stamps and sig's Ive got are from the CFI and the examiner. My flying book is the one that gets sent to the CAA (because thats the one I had first)but I note in my neat book (CAP 407) that its a skills test and note the relevent examiner/instructor licence numbers. If for some reason I lost my original book I donk think the CAA would have any problems accepting the 407
