Komatsu has been sending scale models of their heavy machinery as a thank you gift to long term shareholders since 2015.
The models have typically been 1/87 scale, but for their 100th anniversary celebration back in May, they sent out a set of two 1/72 scale models.
The two models are of a G40 Komatsu type 1 bulldozer (小松1型均土機), and a PC30E-5 electric mini excavator (バッテリー駆動式ミニショベル).
Komatsu was commissioned by the IJN to produce a bulldozer for airfield construction at the end of 1942. Given a very short timeline for turnaround, the G40 bulldozer was essentially a G40 farm tractor fitted with a hydraulic mechanism and bulldozer blade.
The model is most likely based on the G40 bulldozer at the Komatsu Techno Center in Shizuoka, but from various pictures, I get the sense that there were different types of mount for the blade (and different types of blades as well).
The model is mostly diecast metal, with some plastic parts for the hydraulic mechanism, cab, and wheels. The tracks seem to be made of rubber, and are the same color as the bulldozer.
The PC30E-5 was launched last year as a zero emission vehicle, which offered the additional benefits of having low heat, low noise, and reduced vibration output since it uses electrical motors. The vehicle fits in with the Komatsu 100th anniversary theme of environmental protection.
The model is made of diecast metal and plastic. The excavator arm is articulated for motion, and the body can swivel about 45° to each side.
I imagine it's doubtful anyone else will make 1/72 scale models of either of these vehicles ever again.
