Mike, here you suggested (back in 2012) that the list of abbreviations relate to samples taken from the nightdress http://jeremybamberforum.co.uk/index.php/topic,3285.msg128816.html#msg128816
Were that the case, the document would have been headed nightdress instead the 'nightdress' forms part of the list indicating that the other entries relate to other items.
The other entries you refer to, were samples taken from the nightdress, which tested positive for 'A' type blood on 4 occasions, and tested positive for 'O' type blood on five separate occasions! In any event we have the signature of the expert confirming that 'A' and 'O' blood was found to be present on the nightdress! As you know, only Neville Bamber was the only adult victims with
'O' type blood, albeit both child victims also shared
'O' type blood! Technically speaking therefore, Neville Bambers, Daniel and Nicholas Caffells bloods could have all been found on Sheila's nightdress!
At least two different types of 'O' blood were found to be present on Sheila's nightdress, namely 003 and 002+
