Browning did not make ammunition. They contracted another company to make it for them.
They haven't. Special orders are still an option.
Never made in Belguim
They haven't. Some models yes, but, not all.The assembly of Browning shotguns in Herstall,Belguim ended in the year 1976 along with the importation of FN shotguns.Production and importation was switched to the company Miroku of Japan in that year.Some Brownings are now produced in Belguim but assembled in Portugal but this does not apply to all models.
You need a gunsmith.
They haven't.
Unsure of your meaning of "break away shotgun". If you mean breakdown shotguns like double barrels they continue to make several different models.
Lack of demand
Not enough profit.
The Standard Sporting Clays 425 was made from 1995-2001
who makes the westernfield model m550a 12ga shotgun
The last year for the solid rib barrel in a auto-5 shotgun was 1975.
