Cast Aluminum body, with eye level finder and accessory shoe
plus flash contact. An achromatic doublet lens, is my guess.

An Italian made camera from 1953, using 120 film, and providing 24 portrait format
images each 3cm x4.5cm. The film is wound on using two red windows, taking the number
first to one window and then winding forward to the next. The film transport has no rollers
or tension plates anddepends on friction and compression - on this model,not so well - and
winding the last few frames is stiff. The film also does not wind tight, and removing in
a dark room is probably a good idea. :-)

The results (posted in another set) are reasonable given the simple design and optics.
The viewfinder leaves a little to the imagination, also.

Perhaps the most unusual design feature for this camera is the use of a horizontal slit
in the aperture plate for the ƒ16.0 aperture. Wheras ƒ9.0 is a 'normal' circular aperture
on the semi revolving plate, it then becomes a slit when it revolves to the ƒ16 setting.
I have not seen this before. It appears to have been designed this way perhaps because
of space limitations for a separate 'hole' on the small plate.

It also has a very sturdy, screw-in lens cap. Easy to lose, and easy to forget it is on !!
But there's a benefit. The shutter button is so prominent that an additional exposure
on the same frame is somewhat inevitable. No problem, if the cap is on. :-)
