Spat tooth out, or a copy (9)

Ross

I believe the answer is:

photostat

'a copy' is the definition.
(I know that photostat is a type of photocopy)

'spat tooth out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'spat'+'tooth'='spattooth'
'spattooth' anagrammed gives 'PHOTOSTAT'.

'or' is the link.

(Other definitions for photostat that I've seen before include "Copying machine" , "Reproduced copy" .)

I've seen this clue in The Mirror.
