If anyone actually cares to know!
A few weeks ago I asked if anyone knew about these:

Many suggestions given, some more outrageous than others, but nothing definitive. I have now found out what they are, they are cylindrical rules from the 19th or early 20th century.
These were used to rule lines without incurring the danger of dragging the ink down the page - as too often happened with flat rulers. They are made from ebony and were commonly used by draughtsmen and accountants.
