“…paper scales on the cylinder and cross bar…”

Data:

In 1893 L. Manasse, a dealer in photographic equipment and instruments from Chicago, protested against import duties for an “Engineers' slide rule” that was described as:
…intended for use in working out abstruse mathematical calculations. It consists of a movable wood cylinder and wood base mounted with metal; attached to the cylinder and cross bar of the instrument are paper scales by means of which the computations are made…”
…imported per Umbria March 1, 1892…
Note the S/S Umbria of the Cunard line was reported as arriving in New York on March 5, 1892 after leaving Liverpool on February 28, 1892.

Questions:

Which slide rule is described here?
It can't be a Fuller or a Thacher. A Fuller does have paper scales on its body, but not on the metal “bar”. A Thacher does have paper scales on body and “bars”, but more than one bar.
Does anyone have a ca. 1893 L. Manasse instruments catalog?
