This is a slightly rusty example of the Huret Luxe Super Touring (2100ST). Some of its key features are:

• The b-pivot is hanging out a long way from the stop for the cable-outer.
• The various body and parallelogram plates have unfinished edges and are plated with some metal that is relatively cheap and rather dull.
• The hanger plate and most of the bolts are also a bit rough and rather cheaply plated.
• The roller over which the cable runs is carbon black.
• The pulley cage is 83mm long.
• The pulleys have red plastic 'tyres'.
