I don't think so. The first FM models were built under license from FN Herstal, and that continued until the late 1980s, IIRC. FM, in the early 1990s began producing and selling what they called the FM90, which was an unlicensed version of the BHP, with a few changes. Then they produced the M95 Classic until the early 2000s, which was an unlicensed version of the MkIII BHP. Since then, I really don't know if FM continued to build Hi-Power clones.

The early FMs that were produced under license from FN were post-WWII models (MkII?), which is probably what you have.
