The B-24 sn  42-78193 - 454th BG - 737th sqd crashed on 19 may 1944  in the sea very close to my home at Anzio beach  (look MACR 5442) .    In 70's, when I was 12,  I found part of a Martin 250CE Turret  on the beach.  In 2012 I started a web search for identify the aircraft  but the only evidence available to me were:  

1) the finding place :  Lido dei pini beach             (near Anzio) in 1971; 

2) M.A.C.R. 5442

some web sites indicating B24 42-78193 with       'STAR DUST II'  and there is also an aviation       print of A/C (click on the picture below)

 
   
I thought that B-24 42-78193 was 'Star Dust II' but the problem is that 42-78193 A/C was a G-10 NT ( North American / Dallas Production) and after s.n. 42-78189 all this production was in 'NMF' (natural metal) and not in 'OD' (olive drab) camouflage. (look this table)

The definitive evidence that 'Star Dust II' is not the serial number 42-78193 is in this photo taken after Agust 1944 in San Giovanni Airbase (look B24 Star Dust II behind the ME 109)

MACR 5442
