Ok, a conundrum now, after some careful sanding and some not so careful stripping over the last 2 days or so it seems that I've uncovered some markings on the door of my ambulance.
THey are white markings on the Deep Bronze Green, and they appear to have been mostly sanded over before priming and painting of Olive Drab.
The marking is either:
0 1 / 2
D 1 / 2
D I / 2
I am inclined to say that it is 0 1 / 2, but then i have no idea what it means if anything.
Also poses the question, I was going to go with olive drab, but do I go back to bronze green? Wonder if I should be sanding anywhere else, the letters start about 1/2 way down the door, in the middle, but not as tall as say Paul's 2 on the door of his ex airfield ambulance.
I will post pics soon.
