For Sale Data processing book/ enlarging dial

[ann]

As i continue to red-organize the "work area at the lab, i find all sorts of odds and ends long forgotten

this is a wonderful old book (think pre- Darkroom cookbook by Steve Ancell)
Called Black and White Processing Data Book by John Carroll and a "darkroom aid from Kodak. On one side is an enlarging dial to figure out adjustments times for contrast, size, and fstop; on the other side a developing dial for making adjustments for film, temperature, = and - times.

$6 dollars for both , plus shipping. I think this would fall into media which means cheaper mailing
