B-11 parka, jacket identification, help pls.

View attachment 7269 View attachment 7268 View attachment 7267 View attachment 7266 View attachment 7265 View attachment 7264 Is this B-11 jacket an issued one or a repro/civilian one.
Found it in a shop for second hand clothing in Tokyo, this morning.
No ( more AF) decal, splitting hood ( via old Talon). Golden vowen tag.
All others seam OK , IMHO.
Thanks for your opinions.
