Types


So far Tempo-Land Rover types have been divided into 80" and 86" types.
But there were at least two 88" types which were based on a series 2 chassis and produced for the BGS.

Tempo-Land Rover with 80" wheelbase


The base is a Land Rover series 1 LHD export with 80" wheelbase and the old 2.0 litres engine. Frontwings, doors and body have been made of steel by Vidal&Sohn.

BGS-design (almost nothing is known about civil design):

Capstan winch
Two-tone horns
Box for side windows onto bonnet
Locker into each front wing
Turn signal by trafficator
Holder for shovel and hatchet on front wing
Blue lights flashing on left front wing
Extra dashboard for trafficator switch, horn switch and lights flashing switch
Steeldoors
2 Lateral seats for 2 persons
Rear radio mast
