Large cased Long Focus Premo camera. It carries a PREMO label on a circular badge on the top face and the same symbol is repeated in the brass track on the lens board. The manufacturer name is not apparent anywhere.
The structure of the camera is typical of many that were designed to support use of longer lenses. Both the front and rear panels fold down to form a baseboard. The lens standard extends on the front baseboard, as normal, but the rear section pulls out at the back to form the triple extension.
The camera came with three DDS. The ground glass screen is intact. The brass work is in good condition, though showing obvious signs of wear and tarnish. The leather covering is in rather poor condition, separating in places from the wooden body, with some splits and a couple of small sections missing.
The lens/shutter assembly may not be original to the camera.
The example shown in McKeown  is almost identical, except that it is a 4 x 5 version. Note that the Long Focus Premo is very similar in format to the contemporary Reversible Back Premo (though the latter was produced over a shorter period of 1897 - 1900 according to McKeown). However the Long Focus Premo only acquired a reversible back after production ceased of the Reversible Back Premo, which therefore indicates that this example must date to sometime after 1900.
