Kazoobie Kazobo

The All-New Kazoobie Kazobos, hand made in England from shiny horn metal. Available in 7" and 10" models, each has dual resonators and a horn-like kazoo sound. Why is it called "kazobo"? Because its part kazoo and part zobo. A zobo was a kazoo-like horn instrument popular in the early 1900's.

I have one of these, the 10 inch one, but I think it's older. Has a fancy H engraved on the side?
It's so loud though! You really can't realise how loud it is by watching on youtube..
