I have the never built it but have all the scale Proctor kits except the Albi. I have an Antic Bipe kit, too! I've built the VK Triplane and use lots of Proctor fittings in other scratchbuilds. I have been mulling over starting the E-III or D-VII once some other projects can get finished.... you know how that is, lol. Looking fwd to your build.
