Unless I'm missing something - and I'm sure I'll be corrected if I have - Weston meters, at least the ones in my collection are all reflection meters. Thusly Ansel could not have "used incident "metering"" 

Just a thought.
From "Ansel Adams: Some Thoughts About Ansel And About Moonrise", 
by Mary Street Alinder (Copyright 1999 Alinder Gallery):
All was in place, but he could not find his Weston light meter. He remembered that the moon reflects 250 foot candles and he based his exposure upon that fact. He quickly computed a setting of 1/60 at f/8, but with the addition of the filter 
  it became 1/20 at f/8.
Ansel exposed "Moonrise" using incident "metering" (without a meter). Incident metering is a useful tool and doesn't require one to "not 
believe" in the utility and application of spot-metering.

Probably a nit pick but Weston made an incident light attachment for its meters from pretty early on. At least one was available for the Master II. Also, one can get the equivalent of an incident reading by using a gray or white card. If a white card is used the reading is devided by 5 to get the equivalent of an 18% gray card. However, the above text says Adams guessed the exposure. If my memory is correct Adams also said that the negative was underexposed and very difficult to print.
