Greetings Jamo.
Lifelike Decals set 32-018 includes markings for Gabriels BMW Fok DVIIF, 323/18 and are intended for WNW kit 32031.
These markings are similar to those of his early Fok 286/18, but not the same. There are two orange stripes on a blue background aft of the fuselage cross and the stabiliser/elevator has two orange chevrons on a blue background.
The orange fuselage stripe forward of the cross appears the same on both aircraft as does the red Jasta markings.
However, if the lifelike decals may be of use to you drop me a PM and I can post them to you on Friday. (no charge)
cheers
