I think that the Piaggia (sp?) is a 1950's/60's design; It has modern 'opposed' engines rather than radials and the vertical/horizontal tail doesn't have that '30's' "look".
IIRC, I remember reading about that as a new airplane when I first started flying in the '60's
....I have been wrong, though
edit-
I ran the registration number and came up with the following:
PIAGGIO model P.136-L2 serial #224
Air Worthiness certificate issued in 1957
Presently a total of 4 such aircraft in the US Registry (this one is based in Anchorage Alaska)
