Help identifying Japanese company maker of antique flat tin metal toy soldiers WWI

Hi community, I apologize if this is not the right place to post this request, be kind to redirect me if you know.
I have this antique WWI flat tin toys made in Japan, but I have not yet been able to find a maker mark or anything to Identify it.
It is a delicate set, in its original carton case and have not been removed from the original position card.
There is a repeated logo or motif in the front of the case, which I have no idea if it is just a generic shape, or it is related to the maker mark.
Please any help will be greatly appreciated.
Thank you in advance for your time and kind response.
Choose to have a great day!

Model number and made in Japan reference.

Maybe try contacting Bruce Elsass? I bet he would know more.

Thank you for your response.
