We have just added many new codes to the former Testudo English Civil War/Thirty Years War range in "15mm" (more like 18mm) -- pikemen in no armour, pikemen in breastplate and tassets, Croat light cavalry, and two codes without photos yet -- cuirassiers in 3/4 plate with pistols, and cuirassiers in 3/4 plate with lances. (We'll add photos of the cuirassiers asap.)
They are available here:
