Marriage by proxy and... by radio. This carabiniere is marrying his girlfriend from thousands of miles of distance, but can hear her "yes" by the radio... As you can see the "king" has been invited to the ceremony. DVX

Marriage by radio

A pair of Italian Regia Aeronautica’s Fiat G.50bis “Freccia” (Arrow) fighters on servicing (note an air compressor on the right), on the chock and with split flaps down, on a Libyan airfield, perhaps Tripoli Castel Benito airfield. The planes are two different camouflage’s types and also the engine cowling’s camouflage of the aircraft Number 15, that in foreground (note the number over the chock and over the leading edge), is different from those of entire plane. Both are the propeller spinner painted in red and only the half of the engine cowling painted in yellow on the contrary of other G.50s in North Africa with had the entire engine cowling in yellow. Over the engine cowling is clearly visible the sand filter. Victor Sierra
