■Regarding cases from LV1-ver3 onwards Version 3 and later cases are the final version of the LV1, designed with post-purchase maintenance and ease of use in mind, making them easier to use and allowing for longer-term use. Version 2 included an escape valve, but since it was not used in real life and lacked practicality, the valve has been removed in version 3. Some photos show version 2, but this version does not have the circular valve on the side of the case at the 9 o'clock position. ■Specifications Designed, assembled by hand and fully adjustmented in Kawagoe Japan.
