Well here's a turn up for the booklets! Well spotted to Ian R who noticed this for sale on eBay.
It's the 1st class gold from booklets with M12L code. According to the seller the wrapper has a packing date of 22/12/2011. It also exists from the same batch with a short phosphor band at the foot. We don't have any stock yet. My PO received a supply of Jubilee 12 x 1st this morning so the chances of getting any here seem very remote.
