Zeiss Super Ikonta A 530 6x4.5, Carl Zeiss Tessar 7cm F3.5 Lens,Compur Shutter

This auction is for a vintage Zeiss Ikon Super Ikonta model A 530 6x4.5 with a Carl Zeiss Tessar 7cm F3.5 Lens and a Compur shutter, cosmetic condition is very nice condition as can be seen in the photos,
it takes 120 roll film and produces negatives measuring 6x4.5 cm,
shutter is Compur with speeds from 1 sec -1/500 sec, plus B & T,
range finder is bright and working correctly, focusing wheel turns very smoothly, aperture blades are free from oil, aperture blades open and shut as it should, optics are free from fungus and scratch marks, however, there are some surface cleaning marks as well as some dust specks inside, there is a problem with the shutter mechanism as explained below,
shutter lever does cock in position and fires when pushing down the release lever, the problem is that no matter what speed you set the shutter speed at, it will fires at just one speed.
I am therefore offering this item as purely for spares/repairs, please have a good look at the photos and anything you not too sure,please ask me.
