Guys a friend gave me this link to 2500 hi-res photos of normandy in 1944.

http://www.ceris-normandie.com/archi...ndie/PhotosHD/

Unfortunately there is no thumbnails so each photo has to be opened to see what it is. This takes a lot of time as they are large photos. There are a lot of Canadian units shown and a lot are just photos of ruined towns etc but there is a lot of vehicle (both armor & softskins) in amongst them too including the odd CMP or two.

I am only about half way through viewing them myself but I found the photo below (neg p011460). It shows a GMC-CCKW tipper with dual front wheels fitted towing a roller that is laying what looks like plastic sheet.

What is this trailer type machine? Can anyone help with details of it? I may try and do a model of this as it is unusual but only if I can get more details on the trailer.

Cheers
Cliff

Bill & Les if you wait till I finish I will send you discs of the vehicle ones.
