Minetta
The Minetta is a 'HIT type' subminiature camera, made in Japan around 1960. As with its cousins (the Minetta Camera and the Minetta Foreign), it takes 17.5mm film.
According to the Mike Parker's excellent book 'The Hit Project', the Minettas are all classified as QP-style cameras. If anyone has a QP camera for sale, I'd love to add it to the collection.
Other than that, not a lot is known about them. If you can shed some light on any aspect of this wonderful camera, let me know. In the meantime, here are a few relevant resources that may be of interest :

Submin : this is a great collection of these 'HIT type' subminiature cameras
