Pantographs

Before Photoshop, there were mechanical pantographs.  These interesting devices don't show up in my neck of the woods very often.  The good ones have lovely knurled parts.

Finally, a very nice, all-aluminum one, also made in Taiwan but sold through Leichtung Workshops of Cleveland Ohio, one of the original tool mail-order businesses.  It's copyrighted 1988:

As an aside, the term "pantograph" was also used to denote a type of electrical switch!
