There are several sources to check for help. If you purchased the kaleidoscope from a retailer, most BKS retailers are willing to help you find a way to get it repaired. Removable wheels and object cases can sometimes be an easy repair. Damage to the body of a scope can be more difficult and costly. Many artists will offer to do repairs for a reasonable cost plus shipping. Check the advertisements in the BKS newsletter as persons who repair kaleidoscopes advertise there. Sadly, catastrophic damage which effects the mirror system of a sealed chamber or shatters glass are usually not repairable.
