thanks bill - of course due credit goes to you, since i was sitting there with a copy of "HER" trying to get my version to look right.
RE: rapidographs, i still haven't tried a koh-i-noor, which uses an ink reservoir. mine is a rotring, which uses a pressurized ink cartridge instead, making it much more user friendly. you don't need to clean it out as much, and as long as you do a little writing once a week, it doesn't clog. and the smallest size will probably be on one ink cartridge for ten years.
i want to try some other sizes, but i can't draw for shit, so there's really no reason for me to own them except to do tiny lettering.
"a common thread" was numbered with a micron 005, but that was because mjp hadn't opened my eyes yet to the wonder of rapidographs. you can do SO MUCH MORE with a .013 than an 005.
