Can't seem to find any pics to help me answer this:
What color was the floor (the section under the turret)?
Logic would say that it would be OD, since it's open-topped, but I've seen a couple of builds that had the entire interior white, not just the sides / driver's compartment / etc.
Thanks in advance!

. I looked up a couple of discussion threads on the topic and all seemed to say that for the open top vehicles the floor under the turret was OD.

All the interior surfaces you can see looking directly down on the vehicle are absolutely OD.
The driver's area is white.

Thank you, kind sirs!

From B/W photos, the entire basic hull interior was painted white, but then any additional parts, floor compartment doors, etc, ie. anything that was added to the hull interior was in OD.
