Pretty much as it says. Looking for a decent whistle or siren for my 4 1/2" Burrell. Could buy new but wondered if anybody had anything lying about they wanted to exchange for pound notes?
Not quite sure on thread but it is the same size as 1/8 BSP size (will fit but not on the thread looks a bit finer) but not sure what that is in model engineering thread. Maybe someone may know?
