Looking for 15-18mm 1815 British Heavy Dragoons....

I have been looking for some nice 15mm-18mm British Heavy Dragoons of the quality of AB or Eureka for example?  The ones I am looking for have the helmets similar to there French counterparts and NOT the Bicorne.  I am at a loss, I do not want Essex or OG  unless its the last resort. I know of the OG ones but  I am not sure of the quality.  Who am I missing?  I got a unit of 18  beautiful 28mm Perry.s the other day in trade, but they are a "little" big...lol  SO if you know of any other maker of these please let me know.  I have searched around on the net and found only bicorne types other than Essex.

Cheers...
