As it says....
I don't mind new or good condition used. I don't care too much for fancy wood work etc, functionality comes first.
The use will mainly be pest control, but i dare say i'll take it to a clay line up every now and then.
So if you had just £500 for a 12 gauge, what would you be keeping an eye open for?
(please don't send me loads of PM's with offering what you're selling. I'd like to decide what i want first and then look for a good example of it.)
