Recesky Bulb Mode

There is no Bulb mode on a recesky but, a work around is to hold the shutter switch down to a click, opening the shutter, and gently releasing it exposing the film inside.

Recesky Aperture Plate and Vignetting

The default recommendation is to have the aperture plate at the back of the lens however, removing it will give you brighter shots for indoors, and placing it in front of the lens will create more vignetting.
