While repacking family antiques i found an unexposed role of Kodak Kodachrome II Super 8 date develop before 1972 still sealed and never in heat of sunlight.
What are the chances of it still being usable after all these years?

Yah, I know...fat chance.

Nice box and packaging.

Film with an expiration date of 1972, especially KODACHROME (give the curing time prior to release) was probably manufactured around 1970 sometime. IF the film had been stored frozen all these years, it would still be usable albeit some aging artifacts such as loss of color saturation and contrast. However, all that is a moot point here since the K-12 process, along with all things color reversal for any KODACHROME officially is over. The room temp storage would have given the film tremendous age fog over the now nearly 40 years since it was made. But, even so, I've used old films from time to time in testing here, and despite significant loss of filmspeed, they still react enough to light exposure to make images. The film can only be processed as a B&W Negative to realistically expect anything out of it. If you intend to do this, expose it without the Daylight filter and rate it manually if possible at ISO 10. Either way, exposed 'normally' by the camera or manually with some overexposure, you're taking a chance on getting anything usable.....but you never know. I have been pleasantly surprised a couple years ago when I processed some EKTACHROME 160A with an expiration date of 1978 and it still had a fair range of color and density. Of course, storage history is everything, and the radiation that film is exposed to, in addition to heat and time, varies somewhat in all situations. You could just keep it as is as a memento to another era of film...or at the very least, save the box and cartridge after processing. Good luck if you shoot it!
