As Kenny said, Monkey Wards and National Arms? I think it was National Arms but seem to recall mine might be stamped Nato used a barrel with rifling similar to that used by Marlin. MicroGroove was what they called it. More lands and grooves and shallower lands. This makes sense since Marlin briefly offered their model 455 based on an FN Mauser action.

All this discussion about "original" FN Mauser rifles is somewhat pointless since FN sold countless actions to the trade which were used for the basis of "custom" rifles. None of these conform to the FN standards in terms of nomenclature.
