Blowing your own horn

While browsing through the Sax on the Web Forum recently, I realized that many saxophonist members are also keen brass players. Here they proudly display their latest inventions:

Miraphone Double Belled Sax Shaped Trumpet (1950s?)

Martin Williams and his Double Belled Trumpet

Triple Belled Trombone

Double Belled (in series) with a muffler

I am assuming that the picture posters have rights to these pictures. By posting on the SOTW Forum the rights have been extended to the owner of SOTW.

Late addition: Is this a proper use of brass instruments?

This just in (Jul-18-2009):

 

Randy Emerick has joined the trombone section. Watch out, Kid Oreo!
