The pair of Talbot Sambas both has Peugeot Talbot Sport streamers in the front screen. Was this a one make series adding entries to the group A field? One could wonder but my guess is no because the one make series ones were pretty much stock, safety devices apart. I remember we had barely 100 poneys under the bonnet. May be they got a special allowance due to the small displacement and could use some GrpB homologation parts?

Another confusion is often made between the 505 Turbo trophy cars and the real beasts entered either in Production or Super Production.
