Web Site
 

For those not already a where of this site, you may find it interesting.

I found the Crusader Tank SPG conversion particularly interesting (see Argentina section). Presumably these were converted from the Gun Tractor version.

Interesting...
 

I had a look at the Australian, Canadian, Argentinian, Indian and British sections, mainly the softskins and there were of course many omissions but also a large number of errors, not to mention quite a few photographs from books and magazines which were not attributed.
Overall though an interesting site but as an information resource to be treated cautiously.
