I got a question regarding a painting of B-17s (G).
According to this link B17 olive drab colur plates required :
'Most B-17s or B-25s were painted with Olive Drab colour. Until 1943 it was 41 Dark Olive Drab FS30118 or FS34086 or FS(595) 23070 and after 1943 it was ANA 613 Olive Drab - FS34084'
Does anyone know which kind and shade of the primer was used before the final painting?
