There are two models established in the Gear Krieg background:
The LC1/40 Light walker and the LC42 47/32 Medium Walker. The light walker used the drive and legs of a Geramn Walkuere, while the LC42 was based on the heavier Donner/ Thor walker. Following this lead I started the conversion with the legs of the corresponding German walker models.
LC1/40 Light walker
The hull looks IMO similar to a Fiat L6/40 Light Tank - A two-man light tank. I bought the L6/40 kit from Battlefront and used a cupola from the Walkuere kit, added a German MG and an Italian tank driver. Mount the Walkuere legs and your LC1/40 is done.
The resin hull has to be filled with milliput or a piece of plasticard.
Since you get two tanks in the FoW blister I decided to build another one, this time using the turret. One turret received the 20mm Breda while the other one got a flamer / MG from the Shiki kit.
LC42 47/32 Medium Walker
The LC 42 is based on a Semonvente 47/32 su L6/40. This hull really fits the bill. I used again a FoW kit.
Fill the space for the track and add the tankers from the kit. I also used the 47mm gun since the LC42 is using the same gun.
To achieve a heavier look (just adding the hull resulted in a pinheaded model) I added Walkuere arms and grenade launcher.
On the left arm I attached a rare earth magnet to mount a German 3.2 cm gun or a Laser.
Works for me! ;-)
