Thanks for that info Richard, Do they do much of this sort of thing in Oz & have you done this sort of thing yourself.
On another note If they had made Gilbern subframes with Hills know how on rust proofing tubes, there might be a lot more Gilberns around today....although a bit heavier i must admit!
Hills washing lines just never rust, mine's been in our family and 4 house moves for over 40 years and still going strong, it must be a record in these ere parts!! Wasn't it their downfall that they made them too good that they outlasted the buyer?
cheers
