The Wrenn Formula ‘152’ Drivers’ Club was formed in 1962 to promote Wrenn Formula 152. Owners were automatically eligible to join the club and membership entitled them to receive a Badge, a membership card and the quarterly club bulletins which were to be subsequently produced. The application form was printed in Black on Pale Green thin card with a perforated return section for registering. One of these was included within each of the Sets and on sending a Postal Order to Wrenn for 2/6d (12½p in current money) the member could enrol for a year and select to receive either a free brooch or lapel badge, with the type being subject to availability. The first quarterly ‘152’ club bulletin was titled ‘Model Motor Racing’ and was dated March 1963. At this time Wrenn boldly stated on the application form that ‘Formula 152 Motor Racing was already popular in 40 countries’ making it truly international.
