The Luscombe 8 is a series of high-wing, side-by-side-seating monoplanes with
conventional landing gear, designed in 1937 and built by Luscombe Aircraft.

Here is a 1946 Luscombe 8A Silvaire visiting Paso Robles, CA in 2010.


The tail numbers are sure small...not as small as those in pic
luscombe_8a_landed_by_shelbs2.jpg but still, small.

What's the FAA rule on size of aircraft numbers?...anyone know?

12" in most cases; 2" for some classic aircraft.
