Scales see 'lardy' perhaps put on stone (10)

I believe the answer is:

steelyards

'scales' is the definition.
(steelyard is a kind of scale)

'see lardy perhaps put on stone' is the wordplay.
'perhaps' is an anagram indicator.
'put on' says to put letters next to each other.
'stone' becomes 'st'.
'see'+'lardy'='seelardy'
'seelardy' is an anagram of 'eelyards'.
'eelyards' after 'st' is 'STEELYARDS'.

I've seen this clue in The Telegraph.
