The model on the right appears to be a Churchill R75, which does not appear in the catalogue. I suspect that it has just had its turret replaced with one from a Sherman.

B060 Chevrolet 3 ton truck
B63 Bedford office body
B064 Chevrolet petrol tanker (?)

Engraved on the bottom of this model is the serial B326, which does not exist in the current catalogue, and the date 1971. I've taken a guess that the model has been redesignated B064, but it may have been remastered since the 1970s.

B65 Scammel tank transporter

B068 Matador
B069 Scammel Tractor
B082 Leyland Hippo 10-ton truck

I'm not 100% sure this is actually the model referred to by the serial B082. It's definitely a Leyland Hippo, but it's been hollowed out in a way that isn't quite H&R's normal practice, so it may be from another manufacturer.

Edit: OK, I'm now quite sure this isn't the Hippo from Heroics & Ros. I don't know who manufactures this one, but I'll leave it here for the moment.
