Bonfiglio make a range of neat motor/gearboxes but you pay for them! Try a gearbox from a Meccano set, a cheap car kit etc....... . . . good luck! Thank you for the Information, that is a concern that I would burn out the motor it did come with a box of various size gears, will play around with what you stated if it fails then will go with plan B, as Jim Gamble stated it might be better to obtain a setup made for the purpose I may be able to locate a motor designed for window displays that would rotate at 2-4 rev. minute.will need to look around.
