Stockport Vertical Vacuum Engine

Stockport Vertical Vacuum Engine
This Stockport engine kit was purchased from Polly Model Engineering Ltd in England.
The engine was designed by Anthony Mount and is not a true scale model but
 represents a type produced in the 1890s in appearance only.
This type of engine goes by several different names, atmospheric,
flame gulper, flame eater, vacuum engine.
This one has a 27mm 1.062" bore by a 36mm 1.416 stroke.
The piston and cylinder are both made from the supplied cast iron.
(This engine has been a challenge to get it to run but it is now a running engine.)

Castings purchased in January 2020.

  It is not all that complex of an engine but in a sense is almost scratch built.

It is a nice running model.
