Merit 1540 'Standard'


J&L Randal ltd usually sold their steam engines under the SEL brand. However, some were sold under their other brand name Merit. This is one of those. As far as I know, the only differences were the box and the lack of the SEL badge on the Merit branded engines.

The Standard is basically the single cylinder version of the Major. This is the third in size of their range of four stationary engines. Like the Major, the Standard is a neat, compact design and well made. Most of the comments for the Major also apply to the Standard.

The steam feed from the top of the boiler has an in-line lubricator just before the single action oscillating cylinder. The main dimensions are: base - 4 3/4" square, boiler - 4" x 1 1/2" diam, cylinders - 3/16" x 3/8" stroke, flywheel 1 3/4" diam.

The example of this engine in my collection has the slightly less common two sided base. Most of the paintwork but the gold paint on the boiler has been polished off, as is commonly found.

The drawing on the bottom left is taken from a 1950s SEL catalogue.
