Another website mentions that these were produced in India - after the war.
I have 4 different types of these covers, and thought I would share them here.
If anyone else has some of these I would like to see them posted here as well.
TYPE I - "ON-OFFICIAL"

TYPE II – JAP. CHARACTERS – TOP RIGHT – (Red)

TYPE III – JAP. CHARACTERS – TOP RIGHT – (Green)

TYPE IV – No JAP. CHARACTERS – (Black)
