These knights, at 30mm and 15mm, are meant to represent early 13th Century western knights (the full helm ones primarly from the second quarter, but also accurate for the first, and the non-full helmet ones, primarily the first quarter). The non-full helmet knights are intended to represent Aragonese knights from about 1200-1220, with the distinct head band found in Iberian seals and sculptures in Aragon and Navarra.
The horse, rider, shield, lance and pennat are separate for the 30mm ones and come pre-supported and unsupported.
The lance and rider are one piece for the 15mm ones and only come unsupported
