I have the 1970's narrow gap 4-6-4 mm units. (6 is the gap in mm) A few have "gone" over the years and I have replaced them with units made up by The Glass Company on Canvey Island (01268 696688). Not the cheapest but they seem to know their business.
Certainly for narrow gaps I would recommend Guardian coated glass, it improves the narrow gap performance by about half as much again in theory.

OH has said he doesnt think this will work because if the units have gone misty/foggy you will have to take the units out to try and clear them, OH said he would advise just replacing the glass units rather than the whole lot if you are still happy with the surrounding window frames. hope this helps
