I'm showing info in my book that says the Browning Automatic Rifle was based off the Remington 241A & made from 1965-1972 in Herstal, Belgium by FN (Fabrique Nationale) & 1972 to present by Miroku Firearms in Tokyo, Japan.
There are three Grade levels with variations of engraving on the recivers.
Grade I - simple scrollwork
Grade II - small game animal scenes & gold trigger (1972-84, first year only by FN)
Grade III - dog & game bird scenes & gold accents/trigger, extra-fancy walnut stock w/skip-checkering (1972-1984, 1st yr only FN)
The ones from FN are usually worth 2-3 times the price of the Miroku versions.
I'm not just Trigger Happy, I'm Trigger Ecstatic!!
