Are these for an 'A' frame, crane jib or what ?

Couple of pictures of CCKW's with the same, presumably post war, front bumper modifications.
I'm looking for a picture of the 'A' frame, crane jib, snowplough or whatever that these brackets were made to fit. Cheers.

Hi , definetly post war bumper fittings , wartime fittings for the A-frame are mounted on top of the frame , left and right from the winch

Hello yes, I'm almost certain that these are post war. I've seen the traditional 'A' frame mountings, they were situated probably a foot back from the towing hooks and as you say, on top of the chassis rail, although this photo from the Becker book shows a different mounting. I'm inclined to think that these particular mods were more suited to mount a snowplough, I'd just like to get official clarification. There is a picture on http://flickr.com/photos/nounours51/5747116531/in/pool-gmc cckw which shows a front mounted crane jib. This appears to be mounted on the front bumper but it's difficult to be sure as the picture was taken from behind. Thanks for your interest.
