OK smartass Mr Lamb !!!

Perhaps I should have written what were they FROM ?

They appear to have been part of a plane which crashed a loooong time
ago as the props were damaged toward their tips. Someone recovered them
and built a sort of steel framework stillage to hold them upright. They
were thus mounted on the lorry and it's trailer.

There was some evidence of a start to restoration because the tyre had
an overspray of grey paint from where they had painted the strut.

Just curious

Many thanks
Phil
