Hi all - I am new to this forum and located in South Africa, far from available resources.  I am putting out a general call for help.  I have an early Bachmann EMD GP50 diesel loco (Eirie Lakawana) and one of the "stepped" gears in the gearbox has split into 2.  I am hoping that someone out there might even have a replacement gear or complete bogie for me or alternatively can tell me where to source these old parts.  Unfortunately, I do not have a service sheet for this loco but there are 2 of these gears in the motor bogie.   Perhaps someone else has experienced a similar problem and come up with a solution.  Your assistance/guidance would be appreciated.  Andrew
