i am interested to find low rpm gear drives something in the range of 12 to 28 rpm . 12 24 or 115 volts but perfer 12 dc
Got to provide a little more information, Scale? Make? Engine? and also what you are trying to acheive.
If you’re looking for a low RPM output gearhead motor, check
between north west short line and allelectronics i still cannot find what i’m looking for.
the gear drive is not for any scale or engine-- i’m using them to drive conveyors and snake lines on my logging modules., and other slow moving items
Take a look at these:

Run this one at 6 volts, and it will give you around 20 rpm.
