Hi Paul
A very popular kit to build and there are a few variants as far as paint scheme goes. The Panzer II F started to roll off the production line in March 1941. Production stopped at the end of July 1942. A total of 1,004 entered service. They were used mainly on the Eastern Front as a reconnaissance tank but some Panzer II Ausf.F light tanks were sent to Libya as replacements.
If you go for the Eastern front them you are looking at gray - Panzergrau color (RAL 7021)
Revell Tank Grey, Mat (78). As time progressed the Germans would add on field camo patterns with mud and then brown paint Rotbraun (RAL8017)
Revell Rust, Mat (83). Partly in 1942 and then mainly in 1943 the base coat would be Dunkelgelb (RAL 7028)
Revell Sandy Yellow, Mat (16). Also there are examples of them with winter camo.
If you wish to base your model in North Africa then the Germans used brown yellow (Gelbbraun, RAL 8000)
Revell Dark Earth, Mat (82). The colour chosen for camouflaging was green gray (Grau Grün, RAL 7008)
Revell Olive Brown, Mat (86). During 1942 to the end of the conflict in '43 the basic colour was brown (Braun, RAL 8020)
Revell Ochre Brown, Mat (88) and camouflage Grau RAL 7027 (gray) No
Revell exact colour
This was an extensively used model of tank and there are several other camo scheme examples recorded. However what I have described are the main painting schemes. There are several videos on You Tube to help you with the painting and weathering of this model
I dont want to teach you how to suck eggs but if you need a painting guide for tyres, tools, barrels etc let me know. Good luck with the build
