Cat dealer toys

When I was younger, I would go to the Cat dealer to get parts with my Dad. They had toys for sale but I never got one. Seemed they were a little expensive, or so I was told. This was in the mid to late 1970s. My question is who were they made by? Did Cat have an official supplier? These were scaled down Cat models, usually the newest models.
One more thing, what are the dimensions of the ACMOC D9's? Thanks, Jeff.

Most CAT models in the 70's were manufactured by two German company's: NZG and Conrad/Gescha . These were mostly 1:50th scale but I think only three were 1:25th- 941 Traxscavator (NZG) and Conrad/Gescha had a Forklift and a 950 loader. Ertle made the larger 1:25th scale D6,DW15,#12 Grader and a 944 Loader. Check out DHSDiecast.com 's site and you will be able to see many brands of scale models.
