Kerry,
Have a close look at the pic, its home made ! If you are still not convinced, get the VIN off the guy & check on the Russian site. You would also need extra plumbing for the lower temp refrigerant. The semi conductor refrigerant units were not around in 1980.
If a refrigerator option was on offer, we would have seen it down here.
