NOOKY.

This Blip shows one of the many strange and wonderful lens accessories offered by Leitz in the glory days. The NOOKY (catalog name derived from the telex code for that item) was offered in the catalog from 1935 and yes, there are always jokes attached to this particular item... It is a close-up attachment, i.e. an extension tube into which all the high speed lenses that Leitz offered from the earliest days in the 1930s until the 1950s, could be mounted. The device is then attached to the camera itself. Strictly speaking, my particular example is a NOOKY-HESUM because it could be used on the Hector and Summitar lenses as well. This improved model was available from 1939. The little round thing at the top of the image is a supplementary lens to enable the camera's range finder to read down to a reproduction scale of 1:6. The square frame is a mask for the view finder to accurately represent the field of view. We take for granted how easy it is to do macro work now, but in the '30s this was a pretty convenient way to photograph objects as close as about 18" before having to get out the bellows attachment and extension tubes.
