Many letters received after a number of animals shot (7)
I believe the answer is:
postbag
'many letters' is the definition.
'postbag' can be an answer for 'letters' (I've seen this before). I am unsure of the 'many' bit.
'received after a number of animals shot' is the wordplay.
I cannot really understand how this works, but
'after' could be 'post' (prefix meaning after, eg post-war) and 'post' is present in the answer.
'a' is within the answer.
'number' could be 'g' (G is an example) and 'g' is found within the answer.
A single letter 'b' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for postbag that I've seen before include "one's letters" , "carrier for Royal Mail" , "What one receives collectively" , "Letters received" , "All delivered" .)
