Most of capital laid down for equipment (3)
I believe the answer is:
rig
'laid down for equipment' is the definition.
'rig' can be an answer for 'equipment' (rig is a kind of equipment). I am not certain of the 'laid down for' bit.
'most of capital' is the wordplay.
'most of' means to remove the last letter.
'capital' becomes 'riga' (capital of Latvia).
'riga' with its last letter taken away is 'RIG'.
(Other definitions for rig that I've seen before include "Masts, spars and sails on a vessel" , "Gear; fiddle" , "Outfit; fix" , "Manipulate; (oil exploration) apparatus" , "Provide with clothes - for oil well?" .)
