These28mm landsknecht sword arm models are compatible with the spearmen and halberdier set.
https://www.cgtrader.com/3d-print-models/miniatures/other/landsknect-halberdiers-and-spearmenThe set includes 3 arms armed with kreigmessers (swords), and 3 arms armed with katzbalgers (short swords). I intend to make a full set of swordsmen shortly, bit until then this set will allow you to print and build a regiment of landsknecht swordsmen. A sample halberdier is available on thingiverse: https://www.thingiverse.com/thing:4668797. Use this model to verify that these models are of an acceptable scale and style.
