Roofbox plus Roof Bars (Great Linford MK14)

Halfords Roofbox - Approx dimensions: 150L x 100W x 40H (centimetres) which equates to around 450 litres of space
Plus : VW branded roof bars to fit raised rails on roof of vehicle (where there is a visible gap between the rail and the roof)
This is a 20 year old roof box used for family holidays which has been in storage for several years but is serviceable and has keys for locks
The roof bars were used on an old Volkswagen which had raised roof rails but the bars should fit to raised roof rails on any vehicle and they are also width adjustable
There are some minor spots of rust and obvious ageing so they would need a good clean but all items are in good condition for their age, locks on box work, secure locks on roof bars work and they would hopefully be useful to someone
Would like box and bars to go together as a set
