Thanks for your help, mods.
Cash was sent recorded and seller confirmed he had received it.
On 31 July, seller replied to one of my pm's stating the item would be sent on 1 Aug.
On 7 Aug (following my post on this thread), he pm'd me stating the item head been sent a couple of days ago, i.e. 4 or 5 Aug.
Today (9 Aug), I received a package postmarked 7 Aug.
Job done - thanks for your help.
