Vintage circus fairground loudspeaker

Lovely looking unusual vintage loudspeaker, apparently from an old dodgem ride but can't confirm that. It's made from a light steel and is in a nice looking worn condition, it's dinged up with paint flaking but still solid. The lettering loooks like it's been done up a few times over the years. Not functioning as a loudspeaker.
Approx 52cms diameter, 41 cms high and the base is 18x18cms.
