Cromna self-adjusting wrenches

 This is a set of good, heavy, well made adjustable wrenches, made under the name Chromna, each specified in a range of metric sizes. Beautiful things, there doesn't seem to be much information that I can find online, other than the fact they are made in Denmark and licensed to manufacturers in several countries.  Patent 69670 is part of the forged-in text on the handle.

According to this book, that's a complete set of Cromna tools right there.

Thnaks! I've been meaning to buy that book.

The dovetailed lower jaw is pretty impressive, but I bet expensive to produce. I wonder how long they lasted in hard use?

It's funny the things that toolmakers of that era did to get around other maker's patents.
