Sorted out more arms in an antiquarian find (5,7)

I believe the answer is:

roman remains

I'm a little stuck... Click here to teach me more about this clue!

'antiquarian find' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'sorted out more arms in an' is the wordplay.
'sorted out' indicates anagramming the letters.
'more'+'arms'+'in'+'an'='morearmsinan'
'morearmsinan' with letters rearranged gives 'ROMAN REMAINS'.

Can you help me to learn more?

I've seen this clue in The Globe and Mail.
