I realize this is an old thread, but I figured I'd reply.  I finished a 7001 restoration earlier this year that turned out great.

There's really no way to calibrate the AC ranges without an AC calibrator.  I picked up one of these on eBay a few years back that works well-

It is a Fluke 5200A from the 70's.  It is good for the various frequencies required to calibrate vintage meters.  If you want to just calibrate the meter a 60 Hz using a variac and a good digital AC meter you'll find it won't be too far off.

BTW - if anyone else is doing one of these I painstakingly re-generated the meter scale and printed it on photo paper for my restoration.  I would be willing to barter for this image.
