as far as i know, the 47101 is a pre 1999-2000 version which features a snap back and the 47111, the later version, features a screwed back for the back case. also as i far as i remember, there is some modification on the gear train. perhaps, alex can elaborate.

Thank you a.ler and Alex. your a wealth of information
