This kit consisted of replacement pistons and cylinder back covers fitted with neoprene "O" Rings to make maximum use of the steam without wastage. It was recommended that these be used with a displacement lubricator.

Mike Chaney produced his own designs of methylated spirit burner, steam regulator and dead leg lubricator to upgrade and improve on the standard Mamod locomotive.

Complete cylinders were also produced although these inevitably were sold in fewer numbers with owners opting to utilise the excellent "O" ring kit to upgrade the standard Mamod pistons and cylinders instead.
