Beefy type turned up in underwear that often snapped (3,6)
I believe the answer is:
box camera
'that often snapped' is the definition.
(historical kind of camera)
'beefy type turned up in underwear' is the wordplay.
'beefy type' becomes 'ox'.
'turned up' becomes 'came'.
'in' indicates putting letters inside.
'underwear' becomes 'bra' (I've seen this before).
'ox'+'came'='oxcame'
'oxcame' put within 'bra' is 'BOX CAMERA'.
(Other definitions for box camera that I've seen before include "Simple shooter" , "One took pictures" , "one taking pictures" , "Old-fashioned photo taker" , "One taking shots" .)
