Long, unusual brake arm

[rustyjones]

I've had this extra long brake arm(?)for a while now and haven't seen another one in my travels. Does anyone out there know what this goes to? As you can see, it's quite a bit longer than a normal size coaster brake arm. Paul

I think it is for a motorized bicycle Monark marmin ? Whizzer? That arm and a bracket will puts the downward force on a stronger position on frame and is a stronger part of the frame away from the rear dropouts.. want to sell it? Pm me
