[edit] History
Nash & Thomson was established in 1929 at Kingston upon Thames by business partners Archibald Frazer-Nash and Henry Ronald Godfrey. The company was formed to develop the turrets that Frazer Nash had originated, and their designs were consequently numbered in a series prefixed "FN".
Their major competition in the UK was from Boulton Paul who had licensed the designs of the French SAMM company.
In 1996, the remnants were bought by M L Aviation who were themselves subsequently bought by Cobham plc.[1]
