The 1" scale narrow gauge "Dinky" for 3-1/2" gauge track. Designed by Karl Friedrich, it was available from Yankee Shop decades ago. Now available again.
Anyone who owns the book "So You Want To Build a Live Steam Locomotive" by Joe Nelson will know this photo. Due to the popularity of the book, this is perhaps THE most famous photo of the Friends Models narrow gauge "DINKY". This example varies from the published design, but was built from FRIENDS MODELS wheel and cylinder castings, with the balance designed by its builder Robert Hannum. For example, the Stephenson valve gear was custom-installed by Mr. Hannum. The size and general outline shown here will give prospective builders an EXCELLENT idea of the completed engine's look, style, and pulling capability.

1" scale narrow gauge "shifter", for 3-1/2" gauge track
Coal fired; Walschaert valve gear; link and pin couplers. Hand pump; axle pump. Left or right injectors may be fitted by the builder.
This is an excellent engine to learn on. Coal fired; clear and simple prints; will pull 2 adults. May be finished with side tanks as designed, or with a tender of your own design if you so choose. Steams well; light enough to be carried by 1 person; easy to take to other tracks.
This engine is the PERFECT example of "big enough to pull you; small enough to manage". Ideal for a small "up and down" or "loop" track on your property. Since it's not much bigger than a toaster, put it in your auto's backseat and take it to a friend's or a club's track for a day's run.

In his own words, here are some excerpts from Mr. Friedrich's construction notes on his "0-4-0 Dinky Shifter" which he named "UPSY". On September 11th, 1952, Mr. Friedrich penned the following in India ink on vellum paper:
PROTOTYPE: This design is based on industrial locomotives as built by H.K. Porter Co. and "UPSY" represents a medium-sized 0-4-0 Side Tanker. These dinkys were built in almost infinite variety and when you consider the different styles and gauges involved there must have been at least 300 different kinds of 4 wheelers built by H.K. Porter in the days before diesels. This particular design carried its coal under the fireman's set box in the cab, hence no coal bunker is visible. They were also made with a little 4 wheel fuel car. Side tankers and saddle tankers were built from the same patterns, size for size. The sizes ranged from 9" x 14" cylinder and 28" wheels to 18" x 24" cylinders with 46" wheel. All but the smaller sizes were available with either piston or slide valves, and Walschaert or Stevenson valve gear. Only the larger sizes had fluted rods. This design could also be the basis for a 1-1/2" scale locomotive, in which case it would represent a prototype with 10" x 14" cylinders and 30" wheels, 4'-3" wheelbase.
PERFORMANCE: During the 1952 Brotherhood meeting at Danvers, Mass. "UPSY" made several non stop runs around the big loop which is 1800 feet long and includes a 2.5% grade.
HAND PUMP: There is plenty of room in the left side tank for the "Yankee Shop" standard hand pump.
SIDE TANKS: Hold enough water for running on a short up and down track or a small loop. If longer runs are desired a special riding car can be constructed which will hold a couple of gallons of water and also some extra coal.
