Hi Brian,, Guilty, I did not pick up on the word auxiliary, but having suffered the ''intrusion'' you had before, short of taking it off i dont know, you would or maybe not know how often the little scroats return, when we got our first Lifeboat house at mudeford (kindly donated by the Rotary club. Xch) i used to leave the doors open so the public could see ''their'' boat, BIG mistake some pratt actualy stole the boats compass. and they tried to break in, unfortunateley like most vermin they seem to breed well. derek.
