Memory Lane Classics has them for $40. I bought the cheaper one they used to have one about 5 years ago, it fit my repop Schwinn tank, and still works fine. There's a small screw on the horn part that I adjusted to get a lower tone, but it still sounds like a toy buzzer. It's a cool thing to have though. I keep my bike inside, so I haven't had any corrison, but I check it every now and then.
