For a bit more information on the 100D (and 100C), see the October, 1949 
Hewlett Packard Journal:

<http://www.hpl.hp.com/hpjournal/pdfs/IssuePDFs/1949-10.pdf>

Note the accuracy and stability specs:

ACCURACY:  Average stability is within approximately two parts per 
million per week.

STABILITY:  Within one part per million over short time intervals, such 
as required to make a measurement.

The price in 1949 was $600 f.o.b. Palo Alto.

Best regards,

Charles
