or 'Coffeepots 3' we turn to the manufacturer who should really have started the series; De Winton. Stuart Baker produced his splendid drawing of what is probably the best known example, GEORGE HENRY, over five years ago but, just when the editor wanted an art­icle to go with it, he boarded the first plane to the middle-east. It was then discovered that I had taken some detail photographs in May 1976 and could not afford a plane fare; so I got the job. However, my knowledge of De Wintons is somewhat limited so the best I can
do is to quote from Charles E. Lee ('The Penrhyn Railway' - 1972)
"The De Winton locomotives had vertical cylinders bolted to the front of the boiler, driving on to a cranked axle. The wheels were placed inside the framing and were coupled with outside cranks and side rods. The wheel arrangement was 0-4-0, and the wheels were 20in. dia. The De Winton boiler had a general similarity to the boiler fitted into the Sent­inel locomotives and steam wagons, and was a very quick steamer. The boiler pressure was 120Ib. per sq. in. The first three (on the Penrhyn), Lord Penrhyn, Lady Penrhyn and Alice, had cylinders of 10in, stroke; the other four, Georgina, Ina, Kathleen and George Henry, were larger, with 12in. stroke. The locomotives, which were all used for working at the Quarry, were taken out of service or broken up as follow:

Lord Penrhyn     Broken up 1909
Lady Penrhyn             "         1911
Alice                           "         1911
Georgina                     "          1904
Ina                              "          1911
Kathleen             Dismantled 1939
George Henry     Preserved at Towyn

Georgina and Ina were used for shunting at Port Penrhyn until 1883, when they were replaced by Hunslet locomotives. They were then transferred to work in the quarry. The cylinders on George Henry were bin, dia. by 12in. stroke; those taken from Kathleen were 64in. dia., so probably the original size was 6in. dia.. The wheels on Kathleen and George Henry were originally 20in. dia.; the wheelbase was 4ft. 4in. The only dimensions available for the smaller engines are the stroke of the cylinders (10in.) and the diameter of the wheels (20in.). As regards the dates of the De Winton locomotives, Kathleen and George Henry, which were the last to be delivered, had the date 1877 on the maker's plates. There are no maker's numbers. The maker's plates from the other locomotives have been lost or destroyed'
There were, of course, also three 'main line' De Wintons on the Penrhyn and many more on other lines, but this article is really only concerned with George Henry. The drawing should not be used to construct models of other De Winton locos without reference to photos as there are many detail differences from one engine to another. I hope to produce a full De Winton works list with a selection of photographs of various examples, in a future issue.
The more perspicacious readers may have noticed that some details are missing on the drawing. The most notable is the valve gear which, being squeezed between the pistons, is also unfortunately difficult to photograph. Prospective modellers will just have to take a trip to Towyn and see for themselves. Otherwise, I think the photographs should explain most of the more complex lumps of iron. The photos show (amongst other things)     
  1. The locomotive shortly after delivery to Towyn.
  2. The bulge in the frame and the hole for the coal shovel.
  3. The valves on either side of the fire box door in the floor.
  4. A crank on the unsprung (driven) axle, Note also the absence of spokes on the wheels.
  5. The pistons and crossheads. A little of the valve gear may also be seen.
  6. The front end of the pistons, the valve chest and the tank filler.
  7. The chimney and safety valves.
  8. The pressure gauge, the regulator and the reversing quadrant.
