Principally funds are raised for the museum through subscriptions to the BTM and by additional fundraising activities throughout the year such as an annual Classic Car Show & Jumble, a series of popular talks and other events The BTM also fund specific projects such as the restoration of the Pratts petrol pagoda which was opened in October 2010 by Prince Michael of Kent, the replacement of the Test Hill railings and the recreation of the iconic Brooklands Scoreboard.
Following the sale of the land by British Aerospace a charitable trust was formed in 1987 with the intention of starting a Museum dedicated to the Brooklands site and based on the original 1907 clubhouse.
Following negotiations with the new landowners, Gallaghers, the museum was established on thirty acres surrounding the clubhouse including the Members banking and Test Hill.
After the initial renovation, the museum opened in 1991 displaying artifacts from both motoring and aviation related to the Brooklands site.
The president of the BTM was Sir Stirling Moss and he was welcomed at an inaugural dinner held at Brooklands in December 2009.
In 2019 the Bulletin was re-organised and a new editorial team put in place along with new publishers, Hine Marketing, to produce an A4 full-colour quality magazine.
It organises a series of well-received evening lectures for members at Brooklands Museum featuring speakers from the motoring, aviation or related fields.
Angela Hume originally organised the evening talks, then Steve Clarke succeeded her and Harry Sherrard runs them today (2024).
In the past they have been represented at Goodwood Revival and Festival of Speed and Le Mans Classic amongst other more local shows and events.
They are principally produced by Mark Jarman with help from presenters Tim Morris, Martin Gegg and other Museum volunteers.
