Japanese Navy WW2 7.7mm Machine Gun Ammunition

2/25/19 - This is original Japanese Navy WWII 7.7mmx58mm Machine Gun Ammunition. We believe this was used with the Type 92 machine guns that were mounted on naval ships. 50 rounds, un-opened box of tracer cartridges. (The red color on the box indicates tracer). Line 4 Shows 6th month, and 1939 date. Bottom line indicates Yokosuka Naval Arsenal. The box is un-opened and has been sealed in plastic so we presume the cartridges are in tact but not sure of condition.
