Mr. Power YB-001

Early 2010s

This model is obviously inspired by the Wilesco D4/5/6 but is not close enough to be called a copy. In fact it is superior in many ways to the Wilesco.

It appears to be made mostly in stainless steel and diecast (mazac?). The exceptions are the piston, which is brass, and a few minor parts like nuts and bolts which are magnetic so are probably ordinary steel.

The boiler is stainless steel, 51mm diameter x 87mm long. It is heated by a tray type burner which, I assume, is intended to take tablets, but maybe gel. The firebox is stainless steel.

Steam is fed directly to the back of the port face of the oscillating cylinder. The cylinder is 6mm bore x 22mm stroke. The piston is made of brass but I'm not sure about the cylinder. The crankshaft is supported on miniature ball bearings. It has a 69mm diameter diecast flywheel and an 11mm diameter pulley.

The base, despite appearances, is dicast. There is a dummy chimney which also appears to be stainless steel.

Condition as acquired looks almost mint, with only a couple of small chips in the paintwork on the base.
