TURING-WELCHMAN BO REBUILD TRUST CI Charlty No. IZ10268 Patron.. Sir Dermot Turing The most numerous visitors are school parties. TWBRT CIO has developed presentations suitable for school pupi15 most of whom are at Key Stages 3. 4 or 5. In addTtion, parties of university students also visit the gallery. The duration of the visit and its content reflects the varying ages and interests of the students. The other major group of visitors are adults. Demonstrators welcome them and seek to ascertain their level of interest and to demonstrate the artefacts accordingly. This can vary from brief overviews to extended in- depth discussions with enthusiastsl The trust estimates over 22,0(KJ people visited the museum last year. TWBRT CIO relies heavily on the expertise of a small number of skilled trustees and demonstrators who meet each Monday when the museum is closed to visitors to maintain the artefacts. As almost all the equipment is electromechanical this is a continuing process and involves both preventive maintenance and routine servicing as well as fixing the occasional mechanical failure. Most of the trusys expenditure is devoted to maintaining the equipment. Over the period of this report the main artefacts have been accessible to wsitors whenever the museum has been open with demonstrations on well over 90% of opening days. Financial Review TWBRT CIO received a financial donation from the previous unincorporated trust when the latter was wound up. The CIO'S income has come largely from donations made following demonstration visits provided to guests of commercial organisations. The expenditure is mostly devoted to the purchase of spare parts and consumables for the artefacts. TWBRT CIO has a reserve policy to build up sufficient funds to safeguard the Bombe and the other major artefacts in the event of TNMOC not longer being able to house the existing gallery. The trusiees have not identified any signfficant risks to prevent it from continuing its present range of activities in 2026 and beyond.
