Outside cranks for push fitting onto 1.5mm axles. Sized on some I scratchbuilt out of plasticard for a fleischmann 7000 chassis. There is 1.8mm from the axle to the crankpin centres. crankpin holes are 0.9mm diameter.
There are 8 of each: 0.6mm thickness counterweight cranks (intended for a garratt, so modelled on the NGG11/NGG16 cranks), 8 0.7mm thick cranks, and 8 0.5mm plain cranks.
