These are models of a Land Rover Series 2 short wheelbase in T scale (1:450) for use on T scale layouts. All 3 are the same base vehicle, but each is slightly different;
The centre one is is identical to my single Land Rover (which is still available).
The one on the left has a spare wheel on the bonnet.
The one on the right has a van body, with no rear side windows.
These should be printed in FUD in order to acheive the required strength and fine detail needed.
