I don't think the Dignette has a meter or a rangefinder. It's a basic vario model with 3 shutter settings and B, manual aperture settings and a ring with distances on for focussing. The shutter seems to work fine on its different settings.
I'm not sure which model it is but I had a quick look on the web and it seems to be what the Ilford Sportsman was based on. Exactly the same as this but with a Dacora badge.
