I have received these items now and have scanned them in. Could anyone please help with clarifying the extra unknown tags and deciphering the hard to read serial numbers?
Also how do i find out what the serial numbers mean and what aircraft they're off?
Thankyou to Spinpachi for the...
I found this website (Production Indicator in terms of a/the production company),
so i think these instruments are from an aircraft from the Imperial Japanese Army.
