H2X B-17GSH

Who knows whee the letters GSH stand for? They were used for H2X equipped B-17's.

Take a look at this:

I think these were B-17Gs with the H2X radar mounted in the nose behind the chin turret as is shown in a photo above. I think the SH related to this odd radar setup.

Thanks! Yes definitely it refers to the H2X radar. The earlier models were modified F's (top G standard). That would explain the 'G' but now the 'S' and the 'H': where do they stand for...?

Cees,

The question was also discussed here: http://forum.12oclockhigh.net/showthread.php?t=7379

Suggestion is that the SH suffix refers to the radar system.

Groet,

The "S" and "H" may have come from the H2S name for the British radar. As to what they "mean" there is a discussion of the possible meanings of H2S see the "etymology" section here:
