This is a Gerni 260 PX inclined cam disc for a petrol powered cold water pressure washer.
The Gerni 260 PX had a 5.5 Hp Honda motor and was rated at 1750 PSI with a cleaning force of 2.1 kW and a 10 meter hose. This replaced the 118P
In turn, the 260 PX became the G3 P
The G3 P became the Poseidon 3-36 PE and probably the Poseidon 3-39 PE is the closest, current replacement machine.
