Hi. Try phoning Games Workshop mail order on (0115) 91 40000 if you are a UK resident. There are 3 older models available that are actually Grey Knights, or there is the old Librarian model (which I personally prefer and have several of) which serves just as well. The codes and descriptions are below:(posted 9001 days ago)Grey Knight body 1 070204/2 Grey Knight body 2 0702043/5 Grey Knight body 3 0702043/6 Librarian body RTB/6
