The Morris cab and Queen Mary trailer is a company called Sunstar from the far east, which I dont think is going anymore. It was 1/50 scale.
The Pressure Refueller is a stalwart of the Dinky military range. I did find out what real vehicle it is, but cant remember! I do know it is post war. You can find it swapmeets or Ebay, but it is a more desirable one for the Dinky nuts. Mine was substantially trashed and I still paid £15 for it I think. It is a nice vehicle.
They do a nice Scammell crane which is a Pioneer I think. I am going to do a UK recover one in Mickey Mouse when I get round to it.
Dinky was 1/60 scale for their military but some, like the old jeep is 1/48. The trucks are just about 1/56.
Here is
some of my collection of diecast for doing up
