Warmonger Miniatures have recently released these Landsknecht with Zweihänder (Great Swords) and Landsknecht Pikeniere (Pikemen) , available at Warmonger Miniatures website

I was interesred in them as additions to my Warmaster Empire army, whose figures are now out of production. Whilst not Halbediers, they fit in well. I mixed in the two- handed swordsmen with the pike to create a psuedo 'Halbedier' effect.

The Warmaster Halbediers are on the left, in yellow and red.  The Warmonger figures are on the right.
