Airalex, a limited run resin kit company, has one listed on their website as a future release. Some of their other helicopter kits look very detailed. Ordered a T-33 kit from them, but have not build it yet.

Don't know of any others. I think that their is a 1/100 kit out, but not a 1/144 that I am aware of.
