357 Euston Road, London NW1, and was founded in 1887. No. 357 was their new premises - they had previously been located on the north side of the Euston Road between Hampstead Road and George Street.

-"S.T." Engine and Boiler - the engine is as carefully made as the larger engines and was a great favourite for driving Meccano. Whilst the engine was powerful, it was not powerful enough to drive a dynamo. The engine was easy to build for the youngest beginner and was accompanied by simple and very clear building instructions
-"S.T." Steam Plant - a complete plant engine and boiler mounted on fire-proof base. Dimensions 9-inches x 3.25-inches
-Stuart Mill Engine, S50, 0.625-inches bore, 1.25 inches stroke. Described as a perfect model engine that can be built without tools. This is a model of a typical Mill engine such as would have been found in use during the last century (19th century) in the big cotton mills of Northern England. The bed is 8.5-inches long
-The "Sun" Engine - for ordinary or flash steam boilers. 0.75 x 0.75 twin cylinder, single acting, for 4-ft. 6-inches boat or two for 5-foot, 6-inch twin screw boat. Weight - 2-lb., 9-oz., height 4-inches, length (overall) 4.75-inches, width (extreme) 3-inches

-The Stuart Steam Hammer: A Model of Rigby's Patent Steam Hammer - described as a handsome model 10.5-inches high and 9-inches back to front, weight 9-lb. The diameter of the cylinder is 1-inch, stroke 2-inches. It needed only a small boiler and quite a low steam pressure (10lb per square inch is ample. The No. 500 boiler is quite large enough)
-The Stuart Beam Engine - this is not a scale model of any particular prototype, but rather a machine that combines the beautiful lines of some of the famous old engines. The beam engine requires only a small boiler and the No. 500 boiler would exactly suit this model. Dimensions: 1-inch bore, 2-inches stroke, length 13-inches, width 6.5-inches. The beam reaches to a height of 11.5-inches
-Stuart Compressor or Vacuum Pump: Twin Single Acting Cylinders 1-in. x 1-in. Dimensions: weight 5.75-lb, height 5.25-inches, length of crankcase 4.5-inches, width over feet 4.25-inches. Theoretical displacement is 2,200 cubic inches (1.25 cubic feet) per minute at 1,400 r.p.m. For pressures up to 60-lb
-Babcock Boilers. The boilers were advertised as easy to build with hand tools and had a working pressure of 60-lb. No. 500-drum 2.5-inches x 8-inches for the S50. No. 501-drum 2.75-inches x 8-inches for No.10V and 10H engines. No. 504-drum 3.5-inches x 10-inches for the Double 10 and engines up to 1-inch x 1-inch. It would steam Stuart No. 9 just for demonstration purposes
-The "Meteor" High Speed Engine - 0.4375 inch bore x 0.4375 inch stroke. This engine is suitable for boats on fine lines up to 3 feet long and requiring a fair turn of speed. Height 3.75 inches, width 1.875 inches, length 2.75 inches, weight 15 ounces
-No. 496 Twin Drum Boiler - marine or stationary. Height 3.5 inches, length 6.5 inches, width 3.875 inches. Weight with lamp 26 ounces. It was designed for use with the "Meteor" engine and would steam for approximately 25 minutes with one supply of water and spirits
-No. 155 Lubricator and Stop Valve - screwed (3/16) 0.1875 inches x 40 for (5/32) 0.15625 diameter steam pipe
-Stuart Boiler Feed Pump - this pump was constructed entirely of gunmetal and stainless steel and could be set to work at any reasonable speed down to 10 strokes a minute and up to 200. The pump bore is 0.25 inches; the steam cylinder is 0.5 inches x 0.75 inches stroke. The stroke can be shortened by bringing the two set-collars closer together. the main piston valve is moved by an auxiliary "shuttle" piston valve, operated by the arm attached to the piston rod. The suction pipe is 0.25 inches and the delivery pipe is (3/16) 0.1875 inches diameter, the steam pipe being (5/32) 0.15625 inches diameter
-Hand Force Pump - pump barrel and plunger are gunmetal. No. 145/1 -0.375 inches plunger; 0.625 inches stroke, lever 4 inches long. Unions for (3/16) 0.1875 inches pipe

-Model Centrifugal Pumps - two sizes - No. 1 with a 2 inch rotor and No. 2 with a 2.5 inch rotor. They are designed for direct coupling. For pumping a large volume to a moderate height the Centrifugal Pump is unrivalled - it is not capable of great suction lift however (you'd need a piston pump for this). For a suction lift of more than 6 inches, a foot valve must be used which must hang vertically to keep the pump filled. Specification:
No. 1 - Diameter of Casing - 2.5 inches, Centre Height 1 inch, 0.5 inch hose, anti-clockwise rotation, weight 1.25lb, packed weight 2lb
No. 2 - Diameter of Casing - 3 inches, Centre Height 1 inch, 0.75 inch hose, anti-clockwise rotation, 2.25lb weight, packed weight 4lb
TABLES OF DUTIES, PUMP WATER AT WATER LEVEL:

-Pedestal Centrifugal Pumps were sold as a range of pumps for those who wished to purchase the finished article. There were two sizes sold: No. 10 which was of similar capacity to the No. 1; and No. 12, corresponding to the No. 2. Both have centre height of 1.5 inches and were supplied with Vee pulley (1.5 inches effective diameter), or rubber coupling for direct drive
-Electric Pumps: Stuart Models made a range of self-contained electric pumps for those who wished to purchase a complete plant
-S.T. Electric Motor: height 2.5 inches, width 2.375 inches, length 2.5 inches, weight 9 ounces. This electric motor was self-starting with wick-feed lubrication and would run well in either direction
-The Stuart Dynamo would produce alternating current for direct lighting. Height 3 inches, length overall 4 inches, pulley with V groove 0.75 inches in diameter. At 2,500 r.p.m, this would power two 4 volt 1 watt lamps; at 3000 r.p.m, it would power four 4 volt 1 watt lamps; at 5,000 r.p.m it would power eight 4 volt 1 watt lamps. This dynamo was specially designed to be driven by the Stuart Mill Engine, No. 10, "Sun" and other small engines
-The Sandhurst Petrol Engine: 2 inches bore, 3 inches stroke, 150 c.c., speed 900 r.p.m.; 2/3 b.h.p. This engine was designed for the customer who wanted to build an engine of the simplest type due to lack of time and money. The "Sandhurst" had (or has) no governor and no frills and is thoroughly practical and designed for continual work under load such as driving a dynamo or pump. At 900 r.p.m. it can drive a 250-watt Dynamo
-Petrol "Lightweight" Engine (air or water cooled): three-port, two-stroke, 3 b.h.p. at 3,600 r.p.m. Its dimensions are 34.5mm bore x 32mm stroke, 29.9cc, height 7.5 inches, length (over crankshaft) 5.25 inches; weight 3lb 12oz (including flywheel).

-Piston Rings:

-Scale Locomotive Wheel Castings. Stuart Models produced accurate scale reproductions of standard wheels on the locomotives of British Railways. The moulds were made with great care from patterns prepared from drawings of the original wheels with the material being fine close-grained cast-iron, free from blow holes. There were three types of wheel produced: Type A, which is inside driver, Type B which is outside driver, outside coupled and Type C Bogie Tender Wagon:

Unmachined Wheel Castings. These wheels were designed with a liberal allowance of metal. They were cast in the finest quality iron and are soft and homogeneous throughout. They are the wheels used with Stuart Engines:
