This is an optional cable-actuated shutter assembly for the terraPin 6X9 pinhole camera. This will only work on the 6X9 version of the 'slider' insert. A 3mm nut fits into the front plate to receive the tapered thread of the shutter cable release. This mech requires your cable release to actuate at least 10mm. Look for additional photos in the near future. If you have questions about this add-on to the terraPin 6x9 please post in comments - thanks!
