The originals would have included swastikas on all German A/C. In the UK they would anyway.
The only one I spotted here is on the Salamander.
Today's box lids seem to be a mixture of old and new, with the old ones having swastikas erased.
Airfix have recently commissioned a new artist who is much closer to Roy Cross' level than has been evident on some boxes.
Remember the 1/24th scale Stuka box from the 80's? Bloody awful!
