Bearing appropriate identikit (1-3)
I believe the answer is:
e-fit
'identikit' is the definition.
(I've seen this before)
'bearing appropriate' is the wordplay.
'bearing' becomes 'e'.
'appropriate' becomes 'fit' ('fit' can be similar in meaning to 'appropriate').
'e'+'fit'='E-FIT'
(Other definitions for e-fit that I've seen before include "Computer-generated form of identikit image" , "Computer-generated picture for identification" , "Digitally generated representation of a face" , "image of suspect" .)
