Looks quickly at note on old weapons (7)
I believe the answer is:
glances
'looks quickly' is the definition.
'glances' can be an answer for 'looks' (glancing is a kind of looking). I am not certain of the 'quickly' bit.
'note on old weapons' is the wordplay.
'note' becomes 'g' (musical note).
'on' is a charade indicator (letters next to each other) (in a down clue, letters appear on others).
'old weapons' becomes 'lances' (I've seen this in another clue).
'g'+'lances'='GLANCES'
'at' is the link.
Can you help me to learn more?
(Another definition for glances that I've seen is " Quick looks".)
