The instrument was designed by Holton for Maynard Ferguson and was in production for a short period during the 80's. It is now discontinued but can occasionally be found on Ebay (which is where I found mine). It has three valves like a trumpet, but it also has a trombone slide with four positions, enabling some unusual techniques.
