RARE Nikon F Speed Magny RF Polaroid Roll Film Back EXC 3.2x enlargement

  
RARE Mikami Speed Magny RF Polaroid Roll Film Back for the Nikon F. The Speed Magny optical system comprises a magnifying relay lens in combination with a coated field lens and 2 optically flat, surface-coated mirrors. The'RF' the system increases the size of the picture 3.2 times to fill the 3.25 x 4.25 Polaroid format.

Image size and picture angle are the same as if taken with a lens 3.2 times longer than the one used. Use of Speed Magny units requires increases in exposure over those normally indicated by the emulsion speed: an 18x-time increase is necessary. The back is in excellent shape with little sign of use. The metal lens cover that sits where the pressure plate would normally be, had foam originally applied which has disintegrated over time. Some residue remains as shown.

The unit is untested as I don't have any film. Spec sheet in the last photo is not included - just a pdf I found on the web.
