Bf 110 C-4 & C-7 skins:
1) The rounded hatch outlined in green for coolant (Glycol/Water) filling point was only on the left side of the DB 601 cowlings. Not on the right side.
(I will try to edit this post with a photograph later...)
2) Fuselage frames numbers (1 to 18 ) were only stenciled on left side.
Not a big deal but very easy to modify on the void.
