Good luck with your build Bustedwing.
Ccheese, as Wurger stated the Ju88A series was primarily a bomber, but evolved into a multi purpose attack aircraft. The C series a direct conversion of the A series removing the external dive brakes and bomb racks starting out as a ground attack and progressing to a heavy fighter and Night Fighter under the various C designations.
Primarily the fuselage and wings remained fairly constant, while the nose/cockpit, engines and armament changed and evolved for the differing variants. The main visual difference being that the C had a solid nose the A a glass panel nose.
Bustedwings C box top shows the solid nose.
There are many minor variations and modifications in each model that I won't go down that path at this time.....
