Black-jack’s stolen skiing equipment (1,3)
I believe the answer is:
t bar
'skiing equipment' is the definition.
(part of a ski lift)
'black-jack's stolen' is the wordplay.
'black' becomes 'b' (as in pencil classifications).
'jack' becomes 'tar' (I've seen this before).
'stolen' indicates putting letters inside.
'b' put within 'tar' is 'T-BAR'.
(Other definitions for t bar that I've seen before include "beam" , "skiing guide?" .)
