Very cool indeed! I had not heard CSM was doing the HD-1 - was that announced somewhere?
I hope I did not break any industrial secret here, but Edgar could jump in and confirm for CSM.
AFAIK the Hanriot was in their programs before WNW announced one and it was in advanced state, like their Hansa Brandenburg, then the program was delayed to wait for WNW.
Last time that I asked Edgar he confirmed that now they are in the pipes again and they should be among their next kits ... between 6 and 7 months depending on the success of their Armoured Cars.
Also, we shall expect some new version of the Caudron and hopefully, a G.IV in 1/32
so these are happy days for us, WWI modellers: Lukgraph , CSM, Roden but not forget Mikro-Mir and SpecialHobby
