These are all Warlord Games 28 mm resin and metal models.
From left to right, back to front:
- Wespe SPG
- Panzer IV Special with spaced armour
- Hetzer SPATG
- Panzer III Special
They are all in mid to late war camo: the Hetzer is in the late war 'ambush' camo which has lots of contrasting coloured dots.
