They have, in a roundabout way. Eindekker, Albie, tripe, and the DH-2. 2nd time 'round for the DH2. LVG available, as well.
The Albatros is going on it's 5th release, more or less. DV,DVa,the originals, DVa (OAW), Triple kit, and Now MvR DV. WNW have not left the Molds Idle for Long
The Fokker DVII was available in 4 original releases and is now re released as an Early Fokker built bird. They also are selling all of the engine cover sprues enabling building any of the 4 original releases. The W29 was reissued only in an expensive Duelist kit but technically still reissued. As mentioned above the Sopwith Tripe, DH2, and Eindecker are all slated for re issue. I am pretty sure I may have missed a sold out kit that is or has been made available at some point.
