larcher,
No it is not a Browning.
The Grand European Rifles were built on the Winchester 101 20 gauge frame and they also did some combination guns on 12 gauge frames as well.
Like the Winchester 101 shotguns, the Grand European rifles were made in Japan and are a very strong well made rifle.
I have been trying my best to wear one out in 7x65R for years!
It's still going strong however!
