In 2014, the Marussia F1 team went into administration and most of the assets were sold off. This site documents the wind tunnel models, which were sold as a single lot. The pre-2014 parts were mostly missing and a mostly whole 2015 car was sold before being bought back when the team exited administration as Manor F1 in 2015. This is believed to be the largest private collection of F1 wind tunnel models in the world.
All models are available for purchase.
