i believe so as well eric, i get a hint from the red primer. my old man brought some Japanese junk back from ww 2 that looks simular. he was at sewar drome new guinea, & i have great pics posted on pacific wrecks website
www.pacificwrecks.com. he was also on morotai & mindanoa. i'm rather shocked at the going price..... i had an additional 14 pieces of u.s. / japanese aircraft shrapnel / pieces / fabric etc with documentation that i bought from a guy around 1999. cripes!!! did i miss out before ebay & the internet really took off to where it is today. i'm almost embarrassed to tell you what i sold that stuff for then!!! best, tom
