Michael,
Much will depend on the period for which you want to badge the BD. If you have cloth titles it must be after 1943, the year they were officially introduced.
You would then need to establish where and with which formation the unit served and it should then be possible to establish which formation badges are appropriate. Brass titles are not usually found on wartime BD and for any date after Sept 1940 you would also need a pair of RE arm of service strips.
Happy to answer any further questions.
Jon
