how did they keep them from fogging up?

tuck your rifle up against your body as you sleep to keep it warm and prevent condensation? Remove the eyepiece and let it air out with dry air, like next to a fire? I read the original unertl scopes fogged up the morning after their first real combat use in the pacific, and were not used again for the remainder of the campaign.

Hopefully someone will come along and point us to a reference of the actual field tricks employed.

That would help. I wonder if cplstevennorton has any testimony, he's studied USMC use of 1903s extensively.

Letting a scope air out in the humid conditions of the pacific campaign would be reaching some... I hadn't heard about the Unertl scopes fogging up.

I hadn't heard about the Unertl scopes fogging up.

It's been talked about. I confirmed it with reading a firsthand account - I think it was in the book "40 thieves on Saipan".
