Hello again!
Here we are after I went to Gregory Alegi's home and borrowed a book he edited, "In volo per Vienna" (published by the Museo Caproni and the Museo della Guerra of Rovereto).
The 87a was founded the 2nd of february, 1918 on Ansaldo SVAs, thye only model of planes that it had up to the end of the war. The lion of St. Marcus was usually on both sides of the fuselage and it was choosen, together with the name "La Seremissima", because most of the pilots were from the Veneto region (not necessarly from Venice - the commander Capitano Masprone was from verona, Granzarolo from Padova, Finzi from Legnago, Ferrarin from Thiene).
There were two different lions on the planes. The most common is the one above in the picture: the standard lion that we discussed. I had to correct what I wrote before - the book says:
PAX - VAN
TIBI - GELI
MAR - STA
CE E - MEVS
Ther lower one was on the two-seater of Palli and D'Annunzio (SVA 12736) and it was painted by the painter Piero Marussing: the book was closed, the lion was in a square and had a sword in its fist, and the scroll under it had the writing "ITERVM RVDIT LEO" (iterum rudit leo = the lion roars again). Only that two seater had it during the raid over Vienna, but the book depicts also another SVA from "La Serenissima" (SVA 12894) with the same variant, after a forced landing on the top of a house.
The Italian Navy has a flag with a shield that includes the four symbols of the four Maritime Republics of Genoa, Pisa, Amalfi and Venice. There are two flags, one for the civilian fleet and one for the military navy (see bottom of
http://www.radiomarconi.com/marconi/storiabandiera/ ), and they both ave the lion of St. Marcus in the two variants.
The shield of the Italian Air Force (
http://www.aeronautica.difesa.it/htm/stemma.asp) also has four symbols, all after famous WWI Squadriglie: a kind of Chimera with torch after the "X Squadriglia Farman" (recon and lighht bombing), the griffin after 91a (fighters), the four-leaf clover after the "10ª Squadriglia da bombardamento Caproni" (bombers). St. Marcus' lion is here again again to celebrate "La Serenissima", the most famous squadron of recon thanks to the celebrated raid over Vienna. The variant on the flag is Marussing's one, with closed book and sword.
