Hello,

Thanks for details re serial number of the B17.

I see that she was one of the original 12 H2X equipt a/c that had the scanner under the nose.
Serials were-

42-3483...MI-A
42-3484...MI-B
42-3485...MI-C
42-3486...MI-D...MIA 11.01.44
42-3487...MI-E
42-3490...MI-F...MIA 21.06.44
42-3491...MI-G...MIA 06.03.44
42-3492...MI-H
42-3500...MI-J...MIA 04.02.44
42-3511...MI-K
42-30280...MI-L...MIA 22.02.44
42-37745...MI-M

Details from The Mighty Eioghth War Manual, by Freeman.

I would suggest that the "G" is the a/c letter while the "SH" refers to the "H2X".
