I can only imagine what type of "gear" you are trying to restore here and hopes of some kind of out of this world precision performance you're trying to attain. I would also hope your resistance ranges on your meters for this precision measurement are also calibrated to like 10 to the minus 12 parts per million or something like that (LOL). Why not just buy like qty=10 of DigiKey/Mouser PN PPCHF6.98MCT-ND @ 45 cents each and hand select a near spot on 7.0Meg 6.98Meg(nominal) one? I did this with 10 qty of 1% resistors when restoring the Solar condenser tester and got about 3 of each value nailed on the money (using 2 different DVM's for confirmation); the 7 others in the 10 qty lots were like .5% higher and lower/ in between.
