This is the original "Macaura's
Pulsocon" later renamed Macaura's Blood Circulator. British patent
13932. Possibly mid 1880's although in production as late as the
1920s. Fully functional with one of the screw on attachment which is
not seen in the photos. Come with a rare full complement of
paperwork (16 and 58 page booklets and a pamphlet) all in excellent
condition.
