The last DAAM I picked up has a duckbill like none I've seen before.
It is fairly heavy duty and is glossy black, but what makes it really unusual is that it wasn't stuck to the horn or the hose at all, and the only deterioration is at the very edge where it stuck out from under the end of the hose. It still looks nearly new and useable.
Have there been any silicone duckbills produced, reproduction or original, or any made from some other long-lasting material?
