Color Note: The color of new Hemmi plastic cursor bars varied from white to cream to caramel. The color variation is not an effect of aging; in the very last year or two of production the plastic cursor bars were noticeably darker than the white celluloid surface of the rules. We may not be able to match the color of plastic parts.
Spring Note: Some cursors from the 1940s have the spring mounted on a removable plate which is held inside the cursor frame by the cursor glass. Glasses for those cursors are about 1/32" shorter than cursors where the spring is attached directly to the chromed cursor frame; new glasses must be shortened by sanding with ordinary sandpaper to fit.
