§ Please note we have changed the number from 2936S.6a to 2936aS.6 - the basic sheet stamp is a new colour and therefore has the suffix 'a' (2937 is already in use); this booklet stamp is 2936aS, with suffix .6 (2936aS.6)for M16L printing (and 2936aS.7 for M17L printing etc).
This SBP2 reprint is therefore 2936aS.6a.
