Those guns were made in Italy by a company called Luciano Rota, and imported by Navy Arms into the US between 1985 – 1990.
Navy Arms manufactured no firearms of their own, AFAIK - It was a company formed in the late 1950's IIRC, by a guy named Val Forgett Jr, solely to import firearms from outside the US (first BP guns, then cartridge guns).
NA started in Forgett's home, in Teaneck, NJ in 1956-8, then moved to Ridgefield, NJ, and later to Martinsburg, WV in 2005.
