I've had a pair of Schollhorn dividers for many years -- always thought the tightening system was interesting, and the tool particularly sculptural.  A couple of years ago I discovered they were also a) expensive, and b) they were hand fitted (hence the assembly numbers stamped on them).   Then a pair of dividers showed up on eBay.  I just had to have it.

Good price for such lovely calipers.

Talk about speedy delivery!  The callipers arrived by 10:00 this morning, packed to be nearly indestructible.  They're every bit as good as the photo and maybe even a bit better.  10 inches over all length.

Beautiful, both the design and the condition they are in. I definitely would have jumped at them.

Beautiful design.

Yes it is!

Very nice Branson, good example of early white smithing. Where were they made?

The callipers aren't marked with a location, but my dividers say New Haven Connecticut. 
Patent date is January, 1866.
