My new Osprey book, Carolingian Cavalryman AD 768-987, says that Carolingians typically used spears with wings or flanges on the sockets.
I use the Gripping Beast spears for my troops but these are wingless. I have asked on TMP to see if anyone makes these.
I notice that those painted figures which have just gone up on the Artizan site do not have wings but these do seem to be a characteristic and I'd like mine to have them if at all possible (without having to make tiny wings!).
