Title 00015 "Special Purpose Machine" Glass

"This is an airframe of a manufactured article in which a restored article of a junk machine, which was scheduled to be disposed of, is replaced with a ceramic exterior. It is thought that it was used for the work of chemicals or substances that generate high heat, but it does not seem to be used for the original purpose. The exposed parts of the interior were covered with a cloth or rubber-like cover with resistance or heat resistance. The eaves of the head sensor were attached to the aircraft because the influence of light and dirt was unexpected in the environment where the aircraft was operated, but it seems that the material was weak and quickly damaged."
