Well,
I do have a resin kit of the C1 at home scale 1/72, made by MBC models. But,.... looking at it, it appears to me that the wings are wider then the DVII one.
I started in on it some months ago, but resin is not really my thing. the wings have the tendency to bend down for example. Furthermore 1/72 is not my scale. Some time ago I also asked for specific detail foto's for this aicraft, I also advertised over here in Holland. Never had any reaction....
Greetings, Nico Teunissen
