Addendum to p72-73. This appears to be the missing link between the large-fin version of the P 212.02 and the P 212.03. Confusingly, it's also just labelled 'P 212.02', where it appears to be the P 212.02-03 in sequence. In detail terms, besides the shorter dorsal fin and longer rear fuselage, it already has the framed cockpit of the P 212.03 and someone has sketched on a longer nose and the wingtip fins like those of the P 212.03.
