I've seen some info on deciphering the labels with the labels listing the expirations (Showa era where you add 1925 to the number). But I don't have an appropriate 2 digit number (I suspect i should see one in the 40's, this should be a late 60s machine I am thinking, actually brought back from overseas by my brother in law in the early 70s).
Now i also read that some have all Japanese characters, so supecting this is what I have and need to have the labels deciphered to determine the year.
Is there anyone here that is an expert in reading the labels on the front of the machine? They are all very legible.
