I am looking for a specific picture of a prototype high drive tractor which was built around a D9G/H chassis. I saw it in a book about Caterpillar but cant remember which one.It may be a long shot but if anyone has it and can post it here i would be grateful.

Any other prototype pictures would be great such as the fore runners to the rear engine hydrostatic loaders 943-973 or even mono boom wheel loaders.
I must be mad to be posting at this time!!
