56 oz-in tor4que (.3 ft-lb).

OP: unless torque is specified, you'll find gearboxes that weigh from <  
1oz to hundreds of pounds.

You might add a few specs.  Like RPM and horse power?  And are you going to use it to step down or step up?  Surplus Center and Herbach and Rademan are a couple of places I would look.

For instrument-sized stuff, Sterling Instrument (who absorbed W. M. Berg and  
Stock Drive Products) is one of the best places, but their prices may not be  
to your liking.
