If it is in Customs, that's the delay. I had same problem sending my Triumph ECU to a fellow in England who specializes in tweaking them for modded applications. Average turn around time reported by everyone else was a week to 10 days. Mine was lucky enough to be singled out by Customs on the England side, waited almost a month. My English fellow finally intervened and got it through Customs, or I don't know how long it would have languished....
The Goldie replica silencer I ordered from Hitchcocks - ordered on a Sunday evening, arrived at my door in Pennsylvania Thursday that same week. 4 days. That was via ParcelForce also.
