The Soho Myna was a 120 film folding camera made in England by Soho Ltd. from around 1929. There were two models, S.K.12 and All Distance - and several variants of lens plate. Both had an all-metal body, painted in crinkle-finish black.
The All Distance had a simple opening mechanism; pressing a release button on the side opened the door, then there was only a single strut either side holding the door; the lens-plate had to be pulled forward by hand, after opening, to one of two focus stops.
The S.K. 12 was self-erecting, with three struts linking either side of the lens to the body and door which 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 was a tight fit to fold; the viewfinder had to be vertical, and the focus lever moved so that the pointer under the lens was 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.
