A motor maintenance table

Visited I the airfield Uzurano the day before yesterday, being situated at Himeji northern part.
It is not active now, that was not used for more than 75 years since at the end of Great East Asia War. There existed Kawanisi Aircraft Manufacturing Company and a number of fighter was produced including the purpose of Kamikaze Special Attack. Now all the factory constructions were removed and the only airfield remains.
Unusual table was there just beside of stone monuments as shown.
The original design was for the maintenance of the fighter's motor burdened in "Shidenkai" at that period of time. US code name is "George". Also, 2000 Hp motor was called as "Homare" produced by "Nakajima Aircraft" in Tokyo.
These special tables were sold away to unofficial after the war and  this only one has returned back recently.
Piled and peeled paints layers show it's longer history with sadness.
