Where did you find the resistance of the thermistor 'as shipped'? I saw mention of being supplied to the original owner when shipped as well
It was recorded on the original factory cal certificate. I have the original certificates for two of mine. The others had rear panel stickers applied by their original owner (a cal lab).
A properly working, good example should hold 0.1 ppm or better year in, year out. I've seen some that do not meet that, but lots of them do. I'm not aware of any other non-JJ standard that can match it, including most 732Bs. (Some folks think 732As are generally better than 732Bs because they are older and, thus, more stable because better aged. I think there is more to it -- many 732Bs are plenty old enough to have settled down to that level if they are ever going to, but even the older 732Bs don't, in general, seem to exhibit quite the stability of the 732As.)
