Thanks both. I think it is the 4434 knight, not one I have come across before. I can't see how the boot cuffs differ from one another on that picture though. Is that a common problem with this figure, playmofire?
Apart from the suit of armour in 3449, I haven't seen "shiny silver" legs before. PlaymoDB has an incomplete description of this klicky, with the legs (and feet) described as 'unknown colour'.
