By the generosity of a friend, I just received a copy of the Maintenance Handbook for an AN/APT-5 & AN/APT-5A "Carpet" jammer (AN 16-30APT5-3; May 1945). The copy is good, but is a negative (the text is white, the pages black). Has anybody successfully made positive images from such a manual? If so, how? Best, -John =============
