Dicky Howett (Who Was 'Ere!)

Dicky Howett and Tim Quinn were two individuals whose usual occupation was to work a huge bellows in the deep recesses of the Doctor's TARDIS so as to produce the "Vworp! Vworp!" sound whenever it took off or landed.

The two temporarily landed a job creating The Doctor Who Fun Book and were allowed to leave the TARDIS for the duration, though they reluctantly returned to their old job once they were done. (NOTVALID: Outta Space) They had, among other things, researched archeological records of the Doctor's activities throughout pre-1963 Earth history. (NOTVALID: Who Was 'Ere!)
