Robbie: please email me the Spanish list.  Some observations:

THEMODIST -- This sounds like British, as USA ones are "Themodist-
Metrostyle".  If so, between 1922 and 1934 the date was stamped on the
back of the paper (sometimes at the beginning, sometimes the end) in the
form: 385670 or 38 5670 - which would mean August 1923.  1930 onwards the
stamp was cruder and all in purple, and the first two digits are the
year.

KASTONOME stopped production in 1923. (A fascinating system using 80
theme holes, 40 on each side of the tracker bar, and triple valves in the
stack giving instantaneous theme in any chord).

ANIMATIC -- made 1909-39.  Until about 1920 the paper was watermarked
with the date.  I have a 1927 catalog, but roll dates have to be estimated
from the issue numbers.

IMPERIAL LINENIZED stopped production in 1918 when the London factory
burnt down.
