This camera is large; the body, ignoring the controls, is 155 mm wide and 192 mm high; front back, including the lens cover and plate is 172  mm.  The roll film holder adds another 25mm.  The camera weighs about 2.4 kg.

This model has a 6" Taylor Hobson lens fitted to a rising front behind which is the rack and pinion and bellows assembly.  The focusing knob is on the right of the image.

The cloth focal plane shutter claims speeds up 1/1000 second.  Pressing the shutter release raises the mirror which can be locked in the up position.

The case in unmarked but a Thornton Pickard patent number is beside the focusing screen.

The image shows a film holder and the camera back which can fitted to give potrait or landscape format. A mask of either quarter plate or 120 size sits on the focusing screen in matching orientation.

There were several makers of roll-film holders and some of them may be good products.  My experience of a very second-hand one from an unnamed source was that was was not light tight and the film tended to jam and tear.

Results using this camera have been poor mainly due to the roll-film holder but with contributions from my unskilled darkroom technique.

My 120 roll-film holder proved flawed once again.
