There is a house that I walk past a couple of times a week, that I think is let to students. There must have been a change of tenant recently, because there was a mountain of stuff dumped by the dustbin, some of which the dustmen wouldn't take.
Among the bits left in the front garden are two pairs of apparently new coil springs, still shiny and painted black. One pair is a larger diameter than the other.
Where a K Reg Beetle was parked in the front, is now a tatty Peugeot. So I am guessing that the springs are the suspension springs for the Beetle, though having never looked under a Beetle, I don't know how they are sprung.
If anyone wants to have a look, the house is in Bath, and I will e-mail the address if anyone wants it.
