Comparing 1/144 Ko Hi armor version between Shapeway - JARFIR , Dameya Ho Ha and Fairy LKW trucks
However, in term of scale it seems matching the kit Japanese LKW kits from フェアリー企画 ( looks like to me its 1/150 rather than 1/144 )
Compare to Ho Ha kit from Dameya its obvious the rest are a little bit bigger.
If you don't mine the scale I will claim the 1/144 Ko Hi armor version is perfect !
recall the same kit from Yahoo Japan @ 2012
