It isn't very often that there's a transport event of a type nobody has thought of before. But the National Museums of Scotland has come up with the notion of organising, on June 13 and 14, a Scottish Built Rally open to any kind of vehicle - horse-drawn cart or carriage, bicycle, car, motor-cycle, truck, bus, aeroplane - with the correct provenance.

Headquarters for the event will be the Museum of Flight at East Fortune, which is where the Beardmore airship R34, constructed at Dalmuir and Inchinnan, left on the first-ever return flight across the Atlantic.

There will be flying displays and static exhibitions. Road-going vehicles will have a ''proper'' rally on the Saturday, to a rare open day at the National Museums' storage and research facility at Granton.

Some older entries already confirmed include the 1896 Craigievar Express steam carriage from Alford, and the National Museums' own Penman-bodied chain-driven Albion Waggonette.

Thisfine machine was delivered in 1907 to Thomas Barnett of the Templehall Hotel at Morebattle, then passed to the Grants of Tomdoun Hotel in Inverness-shire. It then degenerated into a timber-hauler and disappeared from view.

However, David Findlay of Glasgow registered it in September 1938, and took it on the RSAC's first Veteran Car Run three days later.

Jordanhill Motors owned it post-war, and in 1966 the Albion was reunited with the Grant family. The National Museums bought the car from them in 1991.
