These three books were used in 1915 by three unidentified employees for notes regarding the inspection of experimental powder blank transfers. They are probably part of a larger series, the remainder of which is no longer extant. The entries indicate the varnish lot, blank number, oven number, and the reasons for discarding, such as cracks, thin margins, pull-outs, "birds," pin holes, cracked varnish, and mechanical defects. Some of the notes refer to "special" or "commercial," rather than experimental, blanks. The initials next to the dates on some of the entries may be those of the experimenters.
