Large vertical twin engine - stock code 13071

A large vertical twin engine, standing nearly two feet high and weighing in at a around a hundredweight.

It runs well on air in either direction, feeling like it would do a serious job of work on steam - we could see this one in a large, narrow gauge vertical boiler locomotive!

Fitted with reversing gear and twin boiler feed pumps, The right hand pump moves, but feels tight when stationary - possibly an alignment issue which needs further investigation.
