Quote: Don't forget finnish SAKO High Power and swedish Husqvarna.

Absolutely right, Colt 57 and Coltsman of late '50s used FN actions as did Winslow and H&R (and there are others).
Both Sako and HVA were built with FN actions until they decided to manufacture their own design.
Sako went to a push feed design with a small extractor, Husqvarna 1640 series were the first to have a small ring Mauser type action that was redesigned to reduce machining costs.
Depressed economic climate in Europe after WWII made FN actions affordable.This was not to last as costs quickly escalated in the '60s to the point where they were no longer cost effective to manufacture and discontinued in 1974. FN made small batches of bespoke BMS (Browning Mauser System) rifles that are ornately engraved and sell in the $20K range that are no longer offered. A CNC Mauser 98 action of equivalent quality to an FN costs upwards of $5000 today ( for a Granite Mountain) much more for a Prechtl.
