These Jean Hoefler brand figures are typical of German-made knights. They are late-Medieval fighters of the late 15th to mid-16th century. Note unusual, oversized kneeling figure with knife. Hoefler figures tend toward too-wide heads.
Hoefler's knights have large, round heads. The crossbowman of the top row, and the mounted lancer and standing, bareheaded lancer directly above show some Landsknecht influence. The partial armor, unique thigh armor and unarmored arms of crossbowman and mounted lancer are typical of armored Landsknechts.
These are 6" 'Goldmarx' figures. They include a 13th century Crusader and two late 15th / early 6th Century knights. Marx knights tend to be English in style.
