WW II Japanese Army 1st Class Private Pocket Rank Insignia

Tab is made of tan cotton material with white bar through center with late war pattern collar tab mounted on wool. There is no button type hole, may have been pinned on. Overall a little dirty, the white bar is dirty and this may have been name tag, if so there is nothing there I can see, also may have been branch color. Overall shows wartime wear, still nice looking. Also it looks like it was made from field cap, there is sewn air vent on back. Exc. $70.00
