I am trying to research the career of Flight Lieutenant Walter Richard Shuttleworth DFC,
a navigator with 23, 85, and 605 Squadrons.

On the night of the 18th September 1942 he was flying an Intruder op with F/O Welch
(his usual pilot) in Mosquito YP-H. His log book records:

Patrolled Melun and Bretigny Aerodromes. Attacked Train and S/L with Cannon Fire.

I was wondering if anybody might know what S/L stood for?

I was also wondering if anybody had any further information on Shuttleworth or if they
maight have come across him in ORB's.
