Wikipedia is a great resource... but since any yahoo can make edits, it seems that an effort must be mad to keep the CCKW entry correct and up to date.
Some ass hat had made some edits that are blatantly false:
http://en.wikipedia.org/wiki/GMC_CCKW
Built to 812,262 copies
the W indicated winch for the version with the winch on the front.
The term "Deuce and a Half" is not a post war term and was applied to all 2½ ton cargo trucks.
The logged IP address of this idiot was 90.57.232.146, evidently from France.
These edits were made in Dec/2010.
If you can remember, pop over to the wiki entry and make sure its up to date with facts, not buggered up with some things that some 12 year old read from the plastic model instructions he just got.
