Unknown Woodprint Japanese Boat Flag from the Boxer Rebellion (original) (raw)

This is a scan from an old woodblock print showing two Japanese Naval Flags. One is the usual red sun, but the other is new to me - a red horizontal zigzag over what appears to be a red anchor, on a white field.

This will be used for a book on the forces of the Boxer Uprising.

It looks like the flag of Marine Ministers shown in Flaggenbuch 1939 [neu39]but the difference is that there is only one "wavy" stripe as opposed to two in Flaggenbuch.
