The standard sprue contains:
Four bodies (without legs). Three in chainmail (two identical) and one unarmoured. All with integral saddles.
Six horse halves. Three left, three right of which there are two of each half with one other; meaning two designs of left and two of right -this would make it possible to build four different horses as each half fits with any other.
Three different horses heads. This gives, then, the opportunity to build 12 different horses, given the four different horses.
Six different helmeted heads. Four with chainmail coifs, one with a cloth coif and one with no coif. So you have choices for the four bodies.
Three kite shields. Two have arms attached. None of them have shield bosses (unlike the Crusader ones)
Three round shields. Two have arms attached. All have shield bosses.
Three right arms holding spears. Two overarm grip, one underarm.
Three right arms holding swords.
One right arm with an open hand.
One left arm. For attaching to a shield.
This is largely identicl to the standard sprue as regards horses, weapons and shields. However the top section is different and contains:
A one part casting of a fallen knight on a dead horse.
Three bodies. Two identical in quilted armour and one in scale armour.
One head (identical to one on the main sprue).
One right arm holding a lance with a pennon.
One right arm holding a horn.
One right arm holding a club.
