Hi Jeffrey,
Possibly not but all the reproductions of the pattern that I have seen appear to show the same vertical between 325 and 575 including that in the Operating Manual for the RCA monoscope in Brian's site: http://www.tvcameramuseum.org/pdfs/rca/tk1b-hbook.pdf
Oops! I take that back. That picture does have graded widths.
Thanks, that makes more sense.
