Aero base bar with drop

I have a client in search of an alloy base bar for his track bike. Needs to have some drop to it. UCI not an issue. Does anyone know of a company other than Vision still offering one? Thanks in advance.

Pursuit or ‘bullhorn’ bar

Deda Elementi makes the Crononero Low Rider, plus it comes in several widths, which is not always an option.
Shimano Pro Missile bar is not as deep a drop, only one width (40) but cool nonetheless.

Classic steel on offer from Nitto and Soma as well

Profile has the prosvet. http://www.profile-design.com/product/base-bars/prosvet/

If you are looking for alloy, Profile Design also has the Airwing OS with 35mm of drop:
