These area complete set of \"Master Wheel Patterns\"done in aluminum for a model steam train.These are scaledto actual size = 1.5\" to foot - Original blueprints of the three (light,medium,heavy counterweights) were followed exactly,including the curvature- 16 spokes are correct in number and taper- They measure 8.562\" diameter (with 1\" wide where tire is fitted-allowance is made for machining at back..) Note these are \'Driver Wheel Patterns\'(the centers). These allow a shrink of 1/8\" to the foot when used to make cast iron drivers for the model, these \'centers\' on thefull sized engines were used on some earlyNYC 4-8-2\'salso chosen forthe Timken4-8-4 \"Four Aces\" engine(73\" over tire) The center crankpin boss is correct for a 3.75\"stroke (possible 3.875\")= 3.75\" scales correct to 30\" stroke. These were done for me back in the 1970\'sby a master patternmakerat $4800-The driver set are one piece patterns-see pic.1 - pic.2 shows heavy (main) & medium(intermediate) - pic.3 shows light counterweight driver. These are truly the mostaccurate driver patterns I\'ve seen!. I state used cond\'n however only a few foundry C.I.samples were done for a wall.
