BBC Sound Effects
 

Approximately 16,000 sound clips, some utterly mundane (wind in trees), some are foley effects and others actual recordings. The archive includes many technology or military sounds including recordings of bombs exploding in the London Blitz, rifles firing, Saracen or Saladin armoured cars doing various manoeuvers (noted that both use the same chassis).

Hi Grant

This will take some exploring, thanks for the link.
