Many Blenheims were fitted with rearward-firing Browning "scare guns" which had a limited effect as a deterrent to fighter attacks from behind and outside the reach of the mid-upper turret. This was the original single mounting and ammunition feed. The modification was encouraging enough for it to be adapted to incorporate twin guns in a more angular fitting: this was adopted for operational Blenheims, especially in 2 Group for low-level operations in Europe.
