Maybe (I said maybe
) I can help out...
I know my local hobby shop has a few in stock as he provided me one yesterday on the track. BUT it's a Belgian hobby shop!
He can easily put it in an envelope and send it to you by express which should only take 2 days. That way you might pay a few more £'s but then again you should have it before Friday if you order today or tomorrow!

His phone nr in case you wanna make sure to get it before Friday!

Oh and his name is Theo, a really nice guy and pretty sure he'll do anything he can to help you out!
Hope it helps, good luck anyways!
