Japanese rank slide??

[Kohima]

Can anyone identify the large rank slide with the 'pips'. I have it in the Kohima Museum in York so it was donated by a Burma Veteran of the 2nd Division, so I am assuming that it is Japanese, however we do not have any information on it.

It certainly isn't a British rank slide. it has been suggested that it is INA as it approximates British....but....

Could be a veteran do-it-yourself style souvenir.

1. Thanks but I don't believe that it is. The thing is clearly from the period and what purpose would be served by it?
