From 1960 the Mini range included a estate car version built on a longer wheelbase which it shared with the Mini Van and Pick-up. The estate came badged as either the Austin Seven Countryman or the Morris Mini Minor Traveller, both versions were identical apart from the badges.
The longer wheelbase enabled the Mini estate versions to offer a reasonable load carrying area, which benefited from having a fold flat rear bench seat. Early Countryman / Travellers came with a wood exterior frame at the rear, similar to the Morris Minor Traveller, although the wood was not structural in any way.
The estate Mini's lasted until the 80's and were also available in Clubman fronted versions.
