U.S.A Army models Matchbox or Dinky?

Good research! Thanks for the information John and Chris. 

@john-quilter The APV is an Alvis Saracen FV603 dating from 1952 and is Dinky No. 676. Dinky 670 is a Daimler, which I have as 1941 but it could be 1942.

Terry Hardgrave posted a photo of the 1:1 on Facebook. Dinky did a great job replicating the real tank transporter, except for the lack of dual wheels on the Thorneycroft tractor and trailer. From the photo you will see how large the unit was, compared to nearby cars, so the Dinky was quite smaller than 1:43.
