Just a quick look at one of my distributers (BTI) and I found a few options.

Torelli Aspect carbon
Alpha Q CS-20 carbon
Alpha Q GS-10 carbon

Those all have a 1" threadless option.

also
Ritchey comp carbon
Winwood RT-10- I believe this is a threaded steerer tho

These came from a quick look at QBP.

So if you don't need an exact replica, there are options.
