For those who knew can you tell me if the WWII Arisaka Type 30 bayonet (used on both T38 and T99 rifles) were blued or not? I got many photos of WWII IJA but they're all black and white, and a few color photos of the IJA I have their bayonets weren't blued but these were pre-WWII photos and I want to know if during WWII these were blued can anyone tell me and provide sources of this info please thank you!
