Somewhere over a year ago, I was contacted by someone making some period-accurate blueprints (I forget the exact project, though), meant to replicate the look of something from the American aerospace industry in the 1940’s-50’s. I gathered together a bunch of my scanned blueprints from the era and put together a collection of the title blocks. These are the small grids often visible in the lower righthand corner of blueprints that give all the pertinent info about the drawing. The title blocks not only vary considerably from company to company, but from year to year, division to division, even from one drawing to the next and one draftsman to the next. Sometimes the title blocks were drawn in by the draftsman, sometimes they were printed in advance on the drafting paper, sometimes they were pre-printed “stickers.”
Because someone else might have use for ’em… here ya go, the first of the bunch. This is from a 1944 Bell Aircraft layout diagram of the Model 40 jet fighter, which became the XP-83 (the whole diagram is available as Air Drawing 59 HERE).
