We know that the hydraulic press was installed in the 1920s
†.
Therefore the
Francisco Baró written on the pump (8) must be
F.B. Ginesta
who had founded the
Talleres de Baró company in 1890 — for a bit more about the company see our page
about the open air exhibition in
Castillazuelo.
Pumps in the
Perfecta range (6) counted 2, 3 like here, or 4 cylinders.
A pump with two cylinders can be seen in
Buera, and
Castillazuelo.
A very fine specimen with 3 cylinders — and the glass oil dispensers still present! — is preserved in the oil mill of
Benabarre.
At the time of writing we have never seen the model with 4 cylinders in our study area.
There was also a Suprema range equiped with 6 gears.
