Notes on using these files
Where practical, files are html or jpg or gif graphics. They are usually drawn to fit an 8.5 x 11" page. Experiment with your page margins if you are trying to print images on one page.
Some files, which require lots of detail, are .tif (TIFF) graphics files, with LZH compression enabled and 16kb block size. You may be able to open this file in your browser, using a plug-in like Kodak Imaging Preview. Alternately, you can save the file and open it in most popular word processors or a drawing program.
Some drawings are to actual size. If you print these, you will probably find they are no longer actual size. Each of these drawings has a cross drawn on it that needs to be made 1" by 1". With any luck, you can use a copied to enlarge or reduce the image as required to get the correct scale.
