1. Due to the early date and the sometimes curious nature of finishing at Factory 153, one cannot rule out certainty
the use of older AII lacquers on this scheme, but AMT paints are by far the more likely.
2. This kind of paint demarcation artefact-- which is
usually a line where the paints overlap-- is commonly seen on many
aircraft. This undesirable blemish results when the respective paints
do not blend properly, which in turn may be the result of differences
in chemistry, hardness, surface condition or maturity of the paints.
These artefacts can be commonly seen in many period images, and alas,
also on modern paint finishes; the utmost care is required when
painting aircraft to avoid these problems.
