Hello mapka :
There are no known records of Tokyo production, my guess is 1915 to 1920. It was made at old Tokyo Arsenal before the changeover of production to Kokura.

Well thankyou for the kind remarks. I have to thank my sister in law Christy the Krikinator Keller for the help to boost the computer and get an avatar going. Without her help my new computer would not be a functioning reality.
