A FOUR PILLAR VERTICAL MODEL ENGINE, with Watt's parallel motion, constructed and presented by E. Jekyll, (late of the Grenadier Guards),

The gunmetal, japanned cylinder, 1.75" bore x 3" stroke, has a single beaded annular web, and the steam passage is a separate casting which carries both inlet and exhaust pipes and valve chest. The piston rod drives a three-bearing link with straps, gibs and cotters (one missing). The top and bottom of the links are connected to forked anchor links pivoting on brackets suspended beneath the entablature. The connecting rod has gunmetal ends with a faceted strap, gib and cotter at the big-end.

The crankshaft has a waisted crank, gunmetal governor pulley, eccentric with gunmetal connecting rod, 'Maudslay-style' over-rimmed flywheel and four part wooden pulley wheel.

The bed is fixed to simulated brick and stone base with belt slots and is furnished with a feed pump driven from the right hand side anchor link. Elegantly turned columns support a well shaped and decorated entablature with a gunmetal governor, jockey pulley and pierced
main bearings.

Finished in black with polished brightwork. 33 ins (83cm) high x 18 ins (45cm) wide
