IF you have a 295 series 2.8F you have the last version they made and it should have the Xenotar lens on it and the white face. It should have come set up to recieve the conversion. The back door should have two settings.. one for 35mm and the other for 6x6. If your back door doesn't have that then something is wrong. If you have an old back door on a new camera the pressure plate will not put enough pressure on the film because the spacing will be wrong. Or you might have an old camera with a newer face put on it. Do you have a picture you can post.
Harry Fleenor does the conversions and they don't cost that much if you have a really nice camera which if yours is serial number 29532xx and it is in good shape it should be. In fact putting the 220 switch on the camera can raise the value of the camera more than the cost of the switch... which I think runs something under 300 if I remember right and the cost includes a film transport overhaul. I have a 2957xxx 2.8F myself and it is a fantastic camera with a fantastic lens. I had Harry put a 12/24 switch on mine. But the back door on yours sounds wrong,
