Ditmar - 8 mm and 9,5 mm -1937
The projector made by R. Ditmar G.m.b.H..., Kartnerring 17, Wein 1 Austria.
The projector first appeared in 1937 and returned after the war. The basic design has remained unchanged. Several detail modification to the mechanism has been made. The projector is named Ditmar Duo because of dual gauges projector. This machine has two separate film paths complete with special gates for each of the gauges.
 
It has been available in three versions:
- 16 & 9,5 mm;
- 8 & 9,5 mm;
- 16 & 8 mm.
Our model is 8 & 9.5mm, it is very rare projector as it has not been produced after the war. And our model has a selector knob for desired gauge claw for the different gauges, which mechanism made in projectors after 1938 had not required any claw selection.
Graham Noonan on his web site says about Ditmar projectors : “Initially there were three machines offered : model 2960 for 9.5mm and 16 mm; model 2890 for 8mm and 9.5mm; and model 2860 for 8mm and 16 mm.”-.”-
