I'm telling friends about it and to post here if they want to order.

After measuring the accuracy of the decades, I've decided to build up the better one up to full 6 digits and after finishing it, just for fun I set it as close as possible to the measured 1000000 ohm value and left HP3458A logging data at NPLC100. Here is the result for 2.5 hours and some photos. As you may see, the difference between the set and the actual value here is 23 ohm, or 23ppm from 1M.
Cheers

I would send it back! :-DD

Fortran, the kits came in the mail today. Thanks!
(waiting for some little boxes from China)

suggestion for PeterZ and Fortran :
do the same operation for BCD wheels and capacitor boxes
like explained here : http://kripton2035.free.fr/LabTools/lbt-capacitordec.html
thanks !
