The Soho Myna is a 120 film folding camera made in England by Soho Ltd. from around 1929. There are two models, S.K.12 and All Distance - and several variants of lens plate. Both have an all-metal body, painted in crinkle-finish black.
The All Distance has a simple opening mechanism; pressing a release button on the side opens the door, then there is only a single strut either side holding the door; the lens-plate has to be pulled forward by hand, after opening, to one of two focus stops.
The S.K. 12 is self-erecting, with three struts linking either side of the lens to the body and door which then raised the lens and stretched the bellows as the door was opened. The opening button was moved to the centre of the front and a handle was added on the top. It was focused by a slider on top of the lens plate, marked from 5ft to infinity. The S.K. 12's are a tight fit to fold; the viewfinder has to be vertical, and the focus lever moved so that the pointer under the lens is in the "Set pointer here before closing camera" position, which moved the focus to infinity, retracting the lens as far as possible.
Soho was later merged into Kershaw, and the later Kershaw Eight-20 Penguin models (without an aperture selector) are very similar to the S.K. 12 Myna - except the Myna has a metal key-type winder where the Penguin has a bakelite knob.
